Newbie needs some siggestions from you pros

Hi guys,

I am uk based.
Where would be the best place to look for legal firms that would pay for pay per click advertising on a site for people looking to make and accident/injury claim?
I have experience selling accident claim leads to solicitors already but this has always involved me taking the clients details and selling the leads on. I would rather not have to do any of this but I am not sure how I would go about turning the traffic into cash.

Any advice would be greatly appreciated
