Hi there, it sounds like a nice challenge for my weekend.
I have some experience in Unity and would appreciate the opportunity to take a look at the code and help you get the multiplayer functions working properly.
I have a lot web experience so I'm sure we can find the right technology to create a bridge for your players to connect with.
Thanks for your consideration,

EDIT: After consulting with you on Teamviewer, please note I have increased my bid amount to cover the full scope of work,
