I have been asked by a local pre-school if I would be interested in coming in to shoot portraits of kids in order to sell prints to the parents to raise funds for the school. I would charge the school for the prints, and they would add... well, whatever per print to raise some money. They know my work, and understand that I am a b/w shooter, and not one of those yearbook types. So far, the client work I have done has been children and family portraits. I charge a sitting fee, then scan the negs so they can choose photos online, and then charge for the darkroom prints, depending on size, etc. Pretty simple formula, and works well for small jobs where I don't need a lot of proof prints. I would like to come up with a proposal for them, but I'm trying to come up with an idea on what to charge for the "sitting". I'd probably shoot Xp2 or T400cn, and use a lab, so minimum, I'd charge for film and processing, and we can set a price for the proof prints. Then parents may buy the 4x6 prints from the lab. (Thinking out loud here... if we charge enough for the proofs, then we can maybe cover the film/processing cost) I think I would also offer the fiber based prints that I make for a bit more, if someone is interested in 8x10 or whatever. Again, the school would pay my fee for the print, and charge a bit more to the parents for the print. There are 185 kids at this school, and I need to get at least two to four frames of each over two days. Anyone else do this sort of thing, and how did you approach it?
