Hi, I am looking for private proxies to use with a software I have developed. I will first buy in small numbers (20-50) and later in bulk (500-1000). If any service provider can provide me with what I have given below, then we can start the trial today. This is what I am looking for: 1. Needless to say, these proxies have to be elite. Virgin proxies could work even better. Only thing is it should be affordable. 2. I need the proxies to come from multiple cities & multiple subnets. If I buy 500 or more private proxies, I need atleast 20 cities to choose from. And over 300 subnets. I am mostly interested to buy USA proxies. 3. The proxies should be NON Sequential. That is very important. 4. The proxies should be authenticated by user name & password or by the IP addresses on which I will use them. If it is username & password, then I need the user name & passwords to be same for all. If the proxies are to be authenticated by the IP addresses I use, then I should be able to input atleast 4 IP addresses in your system or panel. Please note that the ISP I use changes the IP address every day. So, I should be able to change the IP address in your system/panel as well. 5. I should be able to change any proxy if it doesn't work. I would need immediate replacement for proxies that don't work. 6. I shall start with 20 private proxies and scale to 50, then 100, 500 & 1000 - this scaling up will be done in a week if the whole testing process goes smooth. So, quality of the proxies would be of paramount importance for us to be able to do business on a long term. If you have a positive answer to all the above points, then lets takl!! Thanks.
