Hello Sir, I am an expert scraper and I have written over 2000 site bots. I have already developed many programs that use proxies (scraper for yell, yellowpages, whitepages...) and all of those work like you suggested, every time request is made with another proxy. Also I am expert in mySql. I would like to talk with you about some details of the project before I make real offer. Check my profile to see that people who worked with me are extremely satisfied with results and speed. I have 100% completion rate and I can start right away. Best regards, Dusan
