The recent business I had as photographer for a local college seems to be coming to an end. The relationship has been rocky since my (unpaid) internship came to an end and I told them they had to pay me to retain my services. Without going into too many details, they seem to be avoiding me about making arrangments for next year and whether or not they will allow me to sell the photos I have taken over the previous year (which was originally their idea since there was some demand for it from some parents and the athletes themselves).
So I was thinking about expanding my business. I have contact information for 23 different colleges and universities, and I would like to send them something as an advertisement.
I was thinking about using a simple business letter to get in contact with these schools. How effective is one? Are their any tips on what I should put into a business letter? Since I've mainly taken pictures at NCAA events, I can't use any of them in an advertisement as it could effect the player's eligability (which also wouldn't look good to potential clients).
