Congrats! As someone who did the same thing over nearly a 2 year period and finally made the leap May 08, good luck!
PS- Sorry but your business plan will never be "finished." You will always need to keep that up to date to apply for credit, loans, show people who may want to invest, but you should take a little time every year (so I'm told) just to update and see how you are following on your goals.
Good luck and keep us up!
Cooking for the love of it.
