Need help creating London DC proxies

As the title says is there any guides available to show me how to create dedicated datacenter proxies ?

How much would each proxy cost ?

There are plenty of youtube video tutorials about creating proxies with squid.

Regarding the costs, you have to factor in both the VPS (Where you will run your proxies) and each IP's individual cost (the IPs you buy from the datacenter and which will become your proxy IPs).

Plenty of scripts avail online if you google
