Now this may hurt a bit but that's not my goal...my goal is to make sure you don't commit financial suicide. Here goes...
If you don't really understand how to start a business (the basics, as you've outlined here) you're chances of any success are incredibly slim...not impossible but highly, highly unlikely. If you didn't have the resolve to read up on starting a business (there are only a few thousand books about it) then you probably haven't created a business plan or a marketing plan or even chatted with an attorney.
This isn't to say you are a stupid or untalented person. I'm sure you are bright and talented. But business is serious...its not a place for someone who has visions of being Bill Gates today (billionaire, private jets etc.) when you'll doubtful get out of the starting blocks of a one man operation.
You've got a fair amount of work to do before your first day of business and a great deal of reading too. Good luck on that...I mean it
