Hello,
I have seen you post and I have to tell you that nobody "serious" will post to do this job. Be careful with the bids you obtain, they are cheating you. I know because I have many sites running with surveys (cpalead, strongerads, etc..) for a long time. What you ask for is already tested by others with not success . Why? because private proxies are too expensive to hold that quantity of surveys per day. There are many other ways to get your surveys completed: tools, seo, viral marketing, etc...but my advice: do not post a project like that one, you will get only fake proposals.
Anyway do not mind my bid, I just put it something to call your attention :)
All the best.
Lydia
