not sure if this is meant for this forum but i'd give it a try:
i was wondering how much would it cost to do some custom programming for php/mysql system like the one at TheAdstop.com
it's for a site that matches webmasters with hosts & networks, rather than what TheAdstop.com does in matching webmasters with advertisers.
Webmasters will be able to register their sites, supply a few details like, url, name, name of site, unique visitors/month, pageviews/month, date site started, topic, objective/aim, number of staff on site, current hosting costs etc
Ad network hosts will be able to browse this listing like at the TheAdstop.com
Also what kind of legal/contractual stuff should i be considering ?
The site will be developed on 2 domains adnetworkhosts.com
