CTL seems really promising. They're the ones who were actually doing Robar's plating. So if you like it, you'll like their product. I'm setting up under my FFL to be a processor/dealer for them. I don't think they intend to accept firearms from the general public, but their dealers will be able to act as a middleman. It doesn't seem like they'll have any gunsmithing services for complex disassembly.
If this all shakes out, I'll gladly accept shipments as I've done for years and be that middle man who can tear it down and reassemble it properly.
