Domain selling service

All i'm, looking for is a simple service that lets people buy domain names. It needs to handle all the issues (payment, checking availability, support etc.). I don't want to make any money, but the prices have to be resonable.

Also, it must work with both USD ($) and GBP (£), and, if possible, EUR (€).

I don't mind if it is on an external wesite (which I will link to), but it needs to be branded as fusionnx.com Hosting Solutions and have a prominient link back to the home page. A couple of small ads (preferebly google) might work for you?

Basically I want to put the code on my site, or put a link to an external site, and have that be the end of it. I want no other input if possible.

Any ideas?

Thanks!
