Hi! and Welcome!
One bit of advice I have is that you get a notebook and use it to jot down ideas, hints, tips, things that seem like a good idea, etc. that you read here, elsewhere on the web, in school, etc. Then, as you start putting the plans together for your business, you'll have all that information in one place to pull from.
Gather marketing information and examples from other people who have a business similar to the one you want to start, so that as you are putting together your marketing plans, you have some ideas for things that you want to do as well as for some that you do not want to do.
Ask any questions, and chime in on the questions asked by others. The more you participate, the more you'll get from these forums.
Start Here. Go Far.
