...assuming you are only considering safe and legal options (if not, that would be an interesting hub question with some wild answers)..like turning your internet hacking skills into a front page wiki-leaks media frenzy...etc.
1. Facebook/Twitter, etc. tweeting a compelling ask for investments....a dollar each from the 1 million "fans" of Whole Earth foods would be....hmmmmmm?
2. Having a hot product or service, with a proven market expanded....here are a few I have watched become successful:
*a Flower roadside bucket stand turns into a floral shop
*a craft fair booth selling handmade burritos turns into a restaurant & catering business
*a mobile coffee cart turns into a chain of pastry/espresso shops
* a pro-bono (free) service that creates buzz and demand and turns a profit if you are good.
...and many more (waiting for your blog on this when the answers fill up the page...)
