We need a robust traffic generator program for extensive testing of our own stats and tracking scripts.

We need a program written that will run a search on Google (and Yahoo, MSN etc) for a particular search term (taken from a list we put into the program,) then if a particular URL is listed in the results, it clicks on the link to visit that site. (Alternatively, instead of searching for a particular term, a list of search URL's could be inputted and the program just runs a random one.)

For each search, the program should use a random proxy, user agent, resolution, OS etc so each visit appears like a real visitor.

The program should also have the feature that once the 'test' visitor is on the final site, the program will make a random percentage of 'visitors' click through to another link on that page.

Should be able to select how many visits sent every hour/day etc.

More details can be provided and we're open to suggestions.
