The Startup Exchange contains a bunch of links and websites to help with (surprise!) starting up a new business. This is fairly focused on the VC and angel-investment funded startup, and therefore a little larger than a PicoBusiness, but if your PicoBusiness is successful, then this would be a great place to look at to help you grow.
In my experience, you want to delay going after other people’s money. For several reasons:
1) By bootstrapping your business, you demonstrate intelligence, creativity, determination and capable leadership
2) By having revenue, you make it hard for someone to argue that you have no business model
3) By having profits (even better!) you make it hard for someone to force you to accept a deal you don’t like
Once you do want to go after investors, don’t forget the 10 lies of the entrepreneur – avoid these at all costs.
