photos for book - prices?

I have been approached to do pet photos for a training book, there will probably be about 50 pics. I don't know what to charge. Any suggestions? I do pet photos for business, and hope to do business with this person in the future, so I don't want to under/over charge.

Thanks

How many books will be printed?

http://photographersindex.com/stockprice.htm is a place to start. From what ive read, this is subjective so theres no right answer.

Using the stock photography calculator, 1/2 page pictures in a textbook for 10k or less copies, it quoted between $175 to $350 per picture. Most companies are cheap so I doubt youd get that for each picture.

I would ask them what size the pictures will be in the books, and how many editions they plan to do, and what they think a fair price would be on a per picture basis. Then work from there. This would give you an idea if they are super cheap or realistic.

Since its 50 pictures they may be expecting a price break. If you reduced the $175 to $50 per picture, thats still $2500 for all 50.

I would also get it in writing as to how many books can be printed with your pictures. So once they meet that you can give them a new price quote that they have to pay or they will have to reshoot the pictures.

my unexperienced 2 cents worth, hehe.

A very basic formula you could use is to multiply the amount you sell your smallest sized print for by the number of copies that will be printed. As a good faith incentive you could offer to discount 10% for every additional print run of their training book. Give your client a per picture per issue price quote so the amount sounds insignificant.
e.g. $5 per image per issue.
If the print run is 1,000 and they use 50 images per issue (crunching numbers) then your end is $250K... adjust the per image price according to what you are comfortable earning from your photography business.

Wow! Congrats!
