What's up! For a quality PCBA producer that can handle low volume orders, I'd recommend checking out pcbasic . They're a smaller shop which is awesome for startups because they really focus on prototypes and low volume production runs vs some of the bigger fabs that like high volumes. I've been super pleased with their build quality on the few boards I've had them assemble.

The one time I ran into an issue is when I cheaped out on components and one of the ceramic caps was totally flaky. But that was totally my bad! Their rework and troubleshooting helped diagnose it quickly. We swapped that cap supplier and it's been smooth sailing since. And even working through that issue, their customer support reps were extremely responsive over email and phone which I really appreciated.
