How much will a PR 3 Site Will be worth even tho it doesnt make anything at all ?

I see you don't know how the process of selling a website... First download all of your files via FTP. Then export your databases if you have. Then turnover all files when payment is received. If you need more help pm me.

I hope that helped. Good luck with your selling!

PM me the details of the domain

Heh i have exactly same problem with one of my websites indeed it is 3 months old with PR3 and some PR2 pages.
