Best proxies for my case

[Fletcher]

So basically I have a bot program which connects to a game and I need to keep the account active for at least 7 days. This game only allows me to connect 6 accounts per IP and most of the datacenter proxies I have tested disconnect after a few days due to the connection being slow or some issue of the kind. What type of proxy would you guys suggest me to use? It can't be something too expensive, my software barely uses any bandwitch. I just need to keep like 100 accounts connected for 7 days
