Hi,
I've been using the Unity engine for over 2 years and have experience with gameplay programming, UI, inputs, shaders, implementing plugins, data serialization and more. I worked on a match-3 type game that can be seen in my freelancer portfolio. I'm currently working on a 3d jrpg style game, I can send you some samples if you contact me.
I'd like to know more about the type of game you want, the mechanics the game has and other features. You don't mention if you have graphics for the game, I don't do graphics myself but I could have an associate do those if that is what you need.
Please contact me so we can establish the scope of the project.
Martin
