Ideablob is a site where you can enter your business plan to raise seed capital of $10,000. http://www.ideablob.com/ There's a new contest each month. Last month Penn State student Aaron Fleishman won for designing a way to use wireless networks to help sick children in the developing world.
The Ideablob site is run by a bank and is in beta, but it looks worthwhile. Before you enter, though, make sure you read all the instructions and also be sure that you really answer the questions that investors ask. I list the top ten questions on my Upstart Business Planning website: http://www.upstartbusinessplanning.com/15601.html
No matter what stage you're in, keep planning for the future, but take action to realize your goals.
