PCB fabrication and assembly service in one?

I assume there are lots of companies that do both under one roof, I looked through the PCB manufactures list and found a couple but

I’m trying to build some simple LED lights (6sq inch, 2 layer) , I was able to get the PCBs from dirtypcbs, but populating them is a absolute pain, 40 tiny SMT components per light. I know a pick n’ place machine would make short order of the task…

I was wondering if anyone had any experience with them, which people would recommend, and what the cost would be.
