Arduino PC Board Game Controller Assembly and Programming

We have a game controller for casino games that is programmed with a pcb board and a arduino board. It works now. It has 12 buttons. that control spin, set bets and paylines, left and right for bonus games, operator keys, and turn lights on and off. We just need someone to test out the code for emf interference and assembly button panels and cabling that is emf shielded. It currently works on usb and we want to change it to work on com. And we need to add a fuse on the pcb so that it doesn't burn up when it gets shouted out. You will have to be local in the Tulsa, Oklahoma area.
