Sorry about starting another "what to charge" thread, but I'm really stumped on this one.
I work for a local company that has quite a few franchises on the west coast, and we are expanding now to the east coast. My position with this company has nothing to do with photography.
However, I was approached by my boss (knowing that I do freelance work) and asked to "contract with me" and bring my camera equipment to a new store opening to take some photos of the interior, signage, etc. They obviously will be using these photos to further market the company to potential franchisees, and perhaps use them in outside advertising and internal promotions.
I plan on charging them a flat fee for the job (somewhat based on what my normal hourly rate for shooting/editing) but I have no idea how to charge for releasing the copyright.. If i SHOULD release the copyright?
