It's such a small market that there's multiple businesses who focus on it?

none of these businesses are hurting - in fact, they're growing. $300k, in the scope of an individual, is a staggering amount of money to most. To a (healthy) business, it's more along the lines of a small/medium capital investment. A lot of the pitch is "You can home-grow this over the course of X years, making occasional mis-steps and paying your expensive engineering salary along the way, with every hour they spend developing this automation thing being an hour they're not spending developing your core product. Alternatively, you can pay Y and have it done in weeks/months while your FTE staff focuses on your core product the entire time. You get to reap the return (on time, on money, on agony, whatever) much faster, you have experts setting it up right the first time, and it's delivered turn-key, with training, to your FTE staff so they can start using it immediately"
There's a reason most engineering talent is under-paid, and it has much to do with the individuals not understanding the business mindset, the actual value of the services they provide to the business, and frankly being snowed by 'big personality, business-oriented' hiring managers. $200k for a talented mid-level engineer with a history of producing should be the 'good start' number, not the 'pie in the sky' one, not just in SV but from sea to shining sea.
