Tough situation. It's still generally true that for offshore dev work companies get what they pay for, so if the company really can replace you with 1 US pm and 2 devs for only $4k/month they probably won't be very good. But they may be able to maintain what you developed so to that extent you might have worked yourself out of a job. At that rate it's also likely that the offshore team may not be as good or as fast as your former client expects, so it's worth keeping in touch in case they need you back. Can you move higher up the "value chain" by doing more technically specialized work that's harder to offshore? Can you generalize what you developed for this company into a SaaS product that you can resell to other companies into the same industry? Realistically it's also just a fact of life that some companies, especially if they're not in high tech themselves, think that offshoring is a silver bullet to cut development costs without any side-effects.
