looking for resident unlimited proxies

I have never seen a provider with what you're looking for. Unlimited proxies are usually expensive and spammed to death because the pool is usually very small. You also won't find a true residential proxy that lasts for over 12 hours because of the nature of rotating residential proxies, the longest will be around 30 minutes but even that's quite rare

Honestly, haven't seen any that short-lived myself, but have you tried rotating mobile proxies? They can give you fresh IPs pretty frequently.
