So this winter, two or three of my gals will be ready to go, and I'd love to try to breed them.

That being said, I'm probably moving this fall. I'm worried that it will interfere with the snakes.

A local reptile store has offered to board my snakes and breed them for me during the time that I'm moving. (and presumably through the breeding process.)

My question is, what is a fair arrangement here?

I would assume that I would pay for food.
Would the trade off be, they keep one/two/some of the snakes produced as payment for breeding/board?

Any thoughts would be greatly appreciated.
