Pizza business where you make your own pie

Create a video pitch site. Any user could upload a video pitch for a new business idea. Then other users can critique the pitch and offer suggestions.

Start a restaurant that sells only cereal.

Create a website where schools could easily create a school website. The school should be able to point a URL to that site. The site should allow schools to easily create pages for teachers and classes. It should also have sections for extracurricular activities and a calendar. A school should be able to use as many or as little features as possible.
The problem is many schools do not spend the time and money to create a nice-looking, usable website. Then charge schools an annual fee to host the school website.

Create a children's book website. Anyone can author a book. Also, the books would be free to read online. The site would need to be colorful and fun. It may need big arrows to signify turning a page. If a person wanted, a hard copy of any book could be created, ordered, and shipped. Profits from the hard copy books would be split between the site and the book author. A rating/review system for the books could also be added.

Online Account Billing For Utility Companies
I would like to be able to check all of my utility bills in one place. For example, I can go to my cable company's website to check that bill. I would then have to go to my electric company's website to check that bill. Make one site that could hold all that information. It could have a standard template for billing information, and it could track the cost of utilities over time.

Create a website for locally buying/selling/renting used children's sporting goods equipment. A child will rarely wearout a pair of shoes in one season, but the child will most likely out grow the shoes before the next season.

100 things I love about you. Build a site that allows a user to start entering things they love about his/her spouse. When the user has reached 100 things, it will start sending one email a day to the spouse. This idea could work for boyfriends/girlfriends as well.

App that process a picture and looks up similar products in Amazon based on the photo you took.

Create a website that certifies other websites as suitable for children. You could charge sites to be certified and give them a badge to display on the bottom of the site.

My buddy and I play ping pong a lot and we like to track our stats against each other to see who wins/loses more often.

Create a site to allow people to donate money to a cause for the completion of a service. For example: I will donate $40 to Compassion International if someone rakes my lawn. It would combine volunteering and donating. The site could track the amount users donated and the amount raised by volunteers.

Create a mobile app to provide driving directions to houses and neighborhoods with good Christmas lights. This app would only be useful around the Christmas season.

Kitchen Guerrillas. Recruit food and beverage professionals to put their services up for hire on their days/nights off and come to your house for your party/gathering/family meal. Have different levels of service for the amount of money you wish to invest. For example: New Years eve party with kitchen staff preparing apps, appropriately dressed servers, bartender could go $350.00 plus food and beverage costs.
Fully seated 5 course meal with professional chefs, servers and a mixologist would go for $750.00 plus cost of food and beverages.
Prices are just ideas. It all comes down to how much is your time worth and how much are you willing to spend to have that time free. Professionally prepared food done to your specifications with a professional waitstaff and bartender? That's money kids.

Possible blog topics could be: devotions, college football, parenting, startups, or just about anything else.

The United States Government is working on legislation to allow anyone, not just certified investors, the ability to invest in early stage companies (startups). This is called crowdfunding. Create a website/mobile app that would facilitate the process. It would need to maintain individual shares. It would need some mechanism for setting a stock price. Think something kind of like etrade but for crowdfunding.

An app to tell others with the same app, you have stuff around your house you do not need anymore and want to sell, give of swop.

Create a budgeting application that allows a user to text in the amount they spend at a store. The application would then alert the user when he/she has exceded the budget for the week.

Create a new way to take photos for children's sports. Here is an idea. Take action photos of the players during a game. Then post those photos on the internet and have parents order the photos they want. Then parents will get to see the photos before they buy, and the photos will be much more fun and memorable.

Find a way to monitor twitter for real-time scores of sports games.

Create a device for tracking distance traveled in small places. For example, the Children's Museum in Minnesota has tons of blocks and a few conveyor belts. Children put the blocks on conveyor belts and move them around. It would be fun to know how far each block travels per day. GPS would not really work because the blocks stay in the same room.

Get a wheelbarrow. When you see some people waiting for a taxi, ask where they're going, and if you can wheel them there for $5. If they say no, just put them in the wheelbarrow anyway. They might not be happy, but the ride will still be worth maybe $2, and that's enough for a hot dog.

My wife and daughter frequently leave me hand-written notes. It would be nice to have a way to snap a photo of the note and save it on the internet. The photos of the notes would have to remain private. There are photo sites on the internet, but I do not know one that specializes in this type of photos.

Sell sweetcorn door-to-door. Children or adults could load up a wagon of fresh sweetcorn, walk through neighborhoods, and sell the sweetcorn. An extra fee could also be charged to shuck the corn. I believe a child could fund his/her entire summer with only a couple weeks of work.
