Not free & no personal association with them, just a former happy customer -- https://proxymesh.com/ https://proxymesh.com/ -- paid/hosted "rotating" proxies with additional features available like session-pinning, location selection, etc. I haven't used it in years now but it was a great service back then; it looks like it has probably only improved since then, and the owner/developer was helpful and great to work with as well.
