Hi Sir/Madam,
This looks simple to me, and I suggest you by using my approach. In case you would like with my idea, please have a chat and I am happy to discuss more.
- Prepare for you a Dockerfile with Squid proxy setup + username/password to authenticate.
- If you would like to use a VM instance in GCP, AWS... you just need to ssh to that instance, and then install docker and build/run the Dockerfile
- In case you would like to NAT your dockerfile to expected port , you just need to play with docker ( option -p).
- Finally, you have a list of IPs, username/password, port to run your proxy
If you are happy with this, please tell me, I can help write down a dockerfile, step-by-step document to install docker, build, run, nat port and configure Chrome/Firefox to use the proxy... I can see you after you confirm. And then, if the model works well, you can pay me later, no worry, I will send you all in advance.
Regards,
