Hello,
I have experience in game design using Unity and for the graphics I am good at Blender and Gimp. Please check my profile.
As for your project, you want a 3D poker game demo (without a menu, options etc.). And important part is it should be a multiplayer poker.
My offer is, I make a Unity game you without a menu but with a 3d desk and cards moving in 3d and the game will allow you and me to play in multiplayer. It will not have a single player mode. And multiplayer support will be handled with photon.
Please contact me via chat to talk further details.
