Each contract is going to be different, based on useage, company etc etc etc.
I don't think there's one way to have a set value, say $10,000. Generally speaking, I use the figure of $15,000 per image. Of course, this goes up for rare images. A couple very rare images I have, I value for $80,000 or more. They also live in a safe deposit box.
You want to make it so they have to pay a licensing fee. Generally, I won't let my images go out for more than a year.
Never, ever, ever give up your copyright. NEVER. NOT FOR
ANY AMOUNT OF
MONEY! If you do this, you give up the possibility to make more money. Let's say you sell a copyright for $50,000. You could probably sell that image again, and again and again for $20k each. After two sales, you would have surpassed the $50,000 you made from selling the copyright.
The most important tip is don't sell yourself short. Don't sell Boeing an image for $50.
Although, I will say I do trade images with airlines sometimes for passes. That is a really good way to get some free travel.
