Congratulations on deciding to start your own business! You've got a long road ahead of you indeed, however, you're on the right track by looking for help on these types of forums. The only thing I can suggest is just to read (**Correction: DEVOUR) as much as you can about having your own business. There is tons of info out there as well as all the resources you need. This website has a lot of good articles on getting started that might help you:

Starting a Business

Also, they post new articles (in all the categories) on a regular basis too so remember to check back.

Hope this helps!
