What sort of leads? If you can, base payments on actual revenue generated.
Them taking on the cost could be good or bad. Starting a PPC campaign is expensive and it takes a little while for your long term CPA to be established. They could be investing their own money because they're extremely confident in their abilities. They could also just be using that as a sales tactic planning to sell you as many cheap non converting leads as possible.
