Which Affiliate Network?

I'm looking to set up an affiliate link for a service that I sell on my site for approximately $400.

Basically, it's kinda of like selling a plumbing service. A customer comes to my website and pays a one time fee, then one of my affiliates performs the work.

Part of the fee goes to me, the remaining goes to the other guy.

So is this possible to set up an affiliate link, and whcih one do you recommend?

Thanks!

Does this mean it's not possible?
