Wow Nancy...that is a pretty broad question, but I am happy to help you as much as possible! Good job on finding what appears to be your "niche". If you love doing this type of work also, you have a win-win situation. I love the saying that goes something ;like this: " If you love your work, you will never work a day in your life!"  This I find to be true, although I havent found anything I enjoyed to do and would alos generate income. With that said, you are off to a good start, however, I will need more clarification on what your goals are for your business. It goes far beyond marketing as you will need a busines license (Most cities require a permit if you work from home) for city, county and state. Before I jump ahead, I do have links to tell you how to get up and riunning, but your question was directed at marketing. COuld you tell me more please on your intent and whether this is to generate a steady income or more as if it was a hobby? Let me know Nancy, and Ill help as much as I can.
