Since you are using Aurora, you'll want a host that specializes in GPT hosting, since Aurora in well known for the utter trash that it is, mysql will burry any OpenVZ node and you will find your VPS suspended, but since it is PTC, that is what you'll buy anyway as you will take the path of least cost, and provider jump until you wake up and realize you are not getting rich at 0.00001 cents per click.
You will also want to have a provider with excellent connectivity to China since 99% of your users will be located there providing your click fraud, and Aurora is one of the last scripts still used with major exploits in it so they can bot the site.
