I'm just start to interested in proxy business too. i guess it can make money depend on your hardwork. about potential, it's kinda ok since many sites would be blocked by schools/work admins everyday so new proxies are required.
A proxy is a site that allows you to access blocked sites (firewalled) by going through another server; for example, getting on MySpace in college/school Hope that helps!
Read this article about starting up in the proxy business and if you need quality proxy hosting, let me know
Flooded market.. And the people that make the programs to stop people going on sites are making better software I doubt PHP proxy will be able to compete with them. The best market at the moment is videos and that will be for a while now.
Hell you can make $20 a day if you know about good ad optimization and know how to advertise in a unique way(what I mean is no advertising on proxy related sites/newsletters etc.) Proxy newsletters and listing sites are flooded with millions of proxies so go to somewhere where there is no proxies being advertised.
I started proxy business a week back and I'm getting $1.5+ everyday from adsense. I think its a quickbuck formula
