Need an Anonymous Proxy Service

I am looking for an anonymous proxy service with at least 255 or more proxies. They need to have high bandwidth and allow more than 25 connections with the same user name and password. These proxies need to not be blocked by the social networks like myspace, hi5, and youtube for creating accounts. Such service should be similar and comparable to the services offered by [login to view URL] and [login to view URL] but their proxies are now blocked by myspace and any account created with their IP's is deleted within 24 hours. These proxies can be private or shared with other paying members, as long as they are not the free proxies that are floating around the internet that go down every few hours. I need them up and running at full speed at all times. I will be looking to pay preferably weekly or monthly. If these proxies are privately owned, I will need to test a few before paying for the lot. WHEN BIDDING PLEASE STATE HOW MUCH FOR HOW MANY PROXIES!
