PC Gaming

You really need a good setup to handle work like that. At a minimum you need stencils, a preheater, targeted hot air, a suction wand, and a drying oven so you don't popcorn the pcbs. It's really uncommon to find anyone who has invested in the tools and who has the experience to pull off core swaps and memory sticks in the states. It's not really untapped, it's more that it's insanely expensive and regulatory issues will crop up the moment you have to take on employees. Most people with that kind of experience and capital are looking to do metal fabrication. It's more consistent money what with the numerous businesses dealing in metal stocks and people needing parts machined, there isn't a ton of local work in repairing electronic stuff on that level and nobody makes any of the raw materials domestically.
