I've been contacted by an art consultant who wants to license some photos for prints.  I'd like to find a standard license agreement that I could use, granting them a one-time right to make a print, but stating that I retain ownership of the images.   And that's all it really needs to say; I've dealt with these people before and they're totally on the up-and-up.

Can  anyone point me to a generic license agreement that I could download and use?
