Good idea! I wish you luck with this. I don't know much about this but I recommend you starting with word of mouth. Let your family and friends know about what you want to do, and start from there. Your clients will let you know what they want and then your business will develop from there. As you start doing this more, your business will grow and develop. You'll learn what works and what you like and what your clients like. Good luck to you!
