If you want the best of the best, a genuinely trained electrical engineer that can solve almost any possible problem, go with "thesteve."
I dunno what his pricing is, I just know he's the best and carries the least amount of risk as far as what happens if the modder you choose couldn't fix something (like damage caused during shipping). You want someone that knows how to diagnose problems at the electrical level with probes, someone who can replace whole chips, someone who has most spare parts at hand, and in this case, someone who designed his own RGB amp circuit (which he did as well), etc. Steve can do all those things and more!
