Why do you try with application IP layer anyway?
I think that encrypted Layer3 solution, something like openvpn with ssl and a
NAT ( and/or Squid ) should suit your needs and is pretty simple.
The appropriate VPS plans I know for this use to cost about $2/month. I'm not
sure but there are cloud providers who supply even hourly-rated virtual
machines ( $0.0X/hour ). And, it's nothing supernatural to ask whoever to set
up such a thing for one-time fee.
