I do mainly retail work, some contractors and designers use my services as well, I have developed long term relationships based on service, quality and mutual respect for one another. I have looked at wholesale but the market isn't appealing to me because of the specialty nature of what we do, A website is the first thing and really figure out what services you feel comfortable enough with to offer professionally and push that people will look for what they want done more than what you hope to do. If you show waht you can do then they will make the connection and ask if you can do what they want. I like the interesting things I am asked to do and many times it is a bit challenging, if it wasn't anybody could do it and it would be at minimum wage not a professional one. Find a niche for your market and sell, sell, and sell some more the work is in the world they just don't know you exist or that you can do what it is they want.
