looking for someone to reprogram eprom Los Angeles

i need a eprom reprogrammed for my home theater. Years ago someone built an ir to rs-232 device, for me. I need to have the eprom updated with new device codes and burned . The developer who did this for me is in the UK and offered instruct someone as to what exactly needs to be done. I don't think it is very complicated for someone who does this sort of thing. Thanks, Ian
