Dear Employer,
I know what it's like to be in your situation as I had been in similiar ones. My idea is that you rent a VPS server (around $5-10 per month) and we build a PHP based proxy on it. Then you, and your firends, will be able to open this website and play games through it. Please message me with details so I can get working as soon as possible.
All of this could be done in a few hours of time.
Kind Regards,
Molnár Antal
