You really should be working on the Android version(you call it Samsung?) and then make the money that way. I just don't see this Kickstarter raising $40,000 when there are currently other alternatives available that DO work via bluetooth.
I suggest you check out Kainy. It is capable of bluetooth controller as full button customization with keybindings. It's main feature is streaming your PC games to your phone, just like how Nvidia shield works. Also supports up to 5 connections.
I think you can use an app called Kainy. I hear the latency isn't quite as good but I have never tried the app myself.
