That's already what we are doing since 2 years on www.hostseeker.com .
Actually we would like to devellop our network and not use the existing one.

By the way, i guess one of the best way to advertise will be to use the Refer Friends feature we setted up lately.
This will allow you to send a mail (which you can customize) to friend with your own referral link in it. Should i say that each referrer will be paid §100 HS. This can be translated in Free Advertising campaigns for your business on the HS Network.
