I've written a lot on other posts about starting up, so find that with the search, but I did forget to mention that if you are asking questions like this, you should definitely consider spending a season working part-time for someone else before you try to learn 'on the job" on your own. You may find you don't like the work, but you will definitely learn the ropes cheaper than doing it for yourself. It's also easier to transition from a job to a new business if you start your own business part time. For example, use your vacation days, one a week, for 10 weeks, to cover a part time gig, and then if you like it enough, ramp up to full time and quit your job. there are many more "tricks of the trade" to learn than you'd think. It's great to be able to approach prospective customers as an "expert" rather than a novice.
