My five business plans are:
1) software that will notify a person by email when an item they're looking for on Craigslist at a maximum price since items go quick when they are posted. also the software would work for ebay when an auction is within an hour of closing. This way a person wouldn't have the risk of getting locked into a bid on one item.
2) According to newspaper article I read in Starbucks, there has been a interest in 3D TV programming due to the success of Avatar. I propose a plan that would use computer aided graphics to turn 2D shows into 3D similar to whats already being done with 3D animation this is would be a close to the same idea when companies started adding color to old black and white movies.
3) Construction estimating software that would account for lineal and square foot material costs and average installation manhours for each phase of the project.
4) Go one step further provide an estimating service using said software and providing information for smaller companies who don't have the resources or time to hire a full time estimator. We would provide competent bids. We could also provide a generic contracts with appropriate addendums specific to that company ie: general contractor will provide forklift for stocking materials. We could also provide pricing and even submit contractor approved bids according to plans and specs.
5)create a remote control device that will start a car from 2000 ft away so that it will be warm and defrosted by the time you go out to the car. The unit in the car would also have timer option that would turn the car on and off throughout the day if necessary for extreme cold environmental conditions.
