I am going to out on a limb and probably get some rocks thrown at me but my answer to the question is most likely "no" you will not be able to earn 1k a month out the gate.
Reason: Far too much competition these days sites are getting blocked by there largest revenue source schools faster. Also there are hardly any good locations left to promote your sites.
By lack of site I am referring to the fact myspace, yahoo and google groups used to be fantastic ways of promoting your site. However these sites are no filled with other proxy owners so your promoting your site to other webmasters and not the right end user. Myspace is semi ok way if you have a large enough list of friends ie. 20k+
Some webmasters offer promotions via email to lists of 50k+ however I dont see any proxy having that type of email list of only proxy users and not webmasters. Proxy 0rg is garbage for promoting these days roughly 1 out of 6 sites in there list are actually a working proxy site.
What does it mean now if you cant spread the word fast enough about your site? Well at the slow trickle of traffic you get from most proxy lists you cant get the word out fast enough and you will be blocked by filtering companies within 2-4 weeks. Once upon a time you could have promoted and seen upwards of 2-3k users a day of english speaking traffic giving the high earning people are still searching for in the proxy gold rush.
The market is very saturated some proxy owners are running 75+ proxy sites and just making around 1k a month. The site that make me the most is my 2 year old proxy site which has established its self. My new ones cant come close to what it makes.
So out the gate I stay with my answer of no unless you can launch 50+ sites and get 1k+ visitors to each one. Many of these proxy owners are still complaining about making only .25-.50 cents a day of a proxy and not evening make back what they have spent to promote them.
Can anyone recommend a proxy host that accepts Paypal (netbuilder member)? I dont know about share proxy hosts or vps but FDCservers takes paypal on dedicated servers
