Does anyone reprogram the main computer for the 2003 Isuzu Rodeo?

What is your question?

The main computer ECM went out on my 2003 Isuzu Rodeo. I found a compatible one on ebay but it needs to be reprogrammed. My mechanic can't do it, I can't find a dealership of any kind who can do it (I live in Dallas), and specialty foreign car shops can't do it. I'm out of ideas. Any help would be greatly appreciated! Thanks.
