Want to Start Private proxies website

I want to start my own private proxies selling website. Following are the requirement. I must be able to sell proxies ranging from 1 proxy to 1000 proxies per month which will be used to create accounts at social networking sites, scrapebox, xrumer, and other seo tools. My proxies should never reveal live ip. I should be able to sell proxies from multiple locations all over world. (Not from all the countries ofcourse.. but atleast from US UK CA Australia) If others can be added with few other bucks then that also i will prefer. How many live ips will be required if i want to create 1000 proxies. If in future i want to increase number of private proxies how can i do it? (guideline needed.) What are the vps requirements for setting up this website. And any legal formalities will i have to complete for setting up this website?? I want support for server setup as well as for website.... Please let me know the budge of both as well as individual budget. Will setup a full milestone and release it after the project is done And full documentation will be needed so that i can change the coding according to my need in future.....
