Click bot

Would like a clickbot that can simulate acuratly users visiting and clicking links on a given website. I would also like for it to have the capability to use proxy servers and automatically change ip addresses after each click. We are trying to creat a testing program for our pay per click sofware. We want to be able to detect bots as compared to real clicks so the more stealthy the bot the better. I am open to a fair and reasonable price. The bot should be non-copywrited software, and should be of the coders own creation. Thank You.
