Mame set up

Hi, I need someone to help me setup my arcade cabinet with a mame system. For the life of me I cant get the games to work. The computer is set up with teamviewer so can be done easily remotely, I just don't have the time to set it up. I have set up gameex on it but can only get about a dozen roms to work properly. If someone has set something like this up before they will find very easy. Or any relatively experienced computer wiz should be able to work it out but that's not me. Any questions please don't hesitate to ask. Fixed price happy to pay hourly after if changes are needed. Kind regards Chris
