thats pretty easy set up. iNstall proxychains and force that all connections go through it
the set up should look like:
OS internet connection > rotating proxy (set to 15 or 60min) > all apps
there are vendors in bhw that can allow you to set custom rotating period.
an other easy solution, is with same proxychain + mubeng
with mubeng (free open source), you add a list of proxies (if you dont want to use rotating proxies) as a txt file and set a port, and using proxychains, the set up would look like:
OS Internet connection > localhost:9876 (mubeng proxy) > all apps
There, it can be set up in like 20 minutes and i saved you lots of time and money
