DNS Geolocation

I have been looking around for a little while but i cant seem to find anything that is cost effective.

I am looking to setup 4 standalone DNS servers, cpanel dns only is the option i want to use because most of my servers run with cpanel.

Does anybody have any idea where i can source some cheap but reliable cpanel dns only servers? from what i can gather it seems most places require a minimum server level to install even cpanel dns onto them.
