I recently ran across MacroFab (https://macrofab.com/), who can do small
orders (quantity: 1) of boards, assembled, for what seems like
reasonable prices. I haven't actually used them, but I did run a recent
board through their process (except for actually ordering), and they
came out with a price of ~$170 for a board that cost me ~$100 to
assemble myself ($35 for board, ~$65 for BoM), so that's not too bad. I
imagine the numbers would be smaller for simpler boards (this one is ~80
components and pretty big -- 110mm x 60mm). The price came down pretty
quick for quantity 3 or 5 or 10, though I don't remember the specifics.
The downside being that you have to be able to upload part-placement
info that is actually correct. Most layout programs don't seem to have
an issue generating it, though -- I just uploaded my gerbers and my
KiCad PCB file and it just ran with it.
FWIW, it's not that hard to do even fine-pitch SMD stuff onesself.
There's a little bit of startup cost (you really want to build a proper
reflow toaster), but with high quality PCBs available via OSHPark (and
fast! My *four layer* board was ~10 days), and quality stencils
available via OSHStencils, doing even fine-pitch SMD work at home is
surprisingly easy. In most simple cases, you don't even need the stencils...
