I think you are getting a good deal already, USD 165 for 1000 boards.
Many assemblers won't even be interested in such a small lot.

The numbers quoted were per-hour, not totals.

Oh, that would be expensive. I would do it manually. A skillful
assembler (human) can handle them easily. I brought a lighted
magnifying glass for a worker once, but she prefers naked eye and
natural lighting. For $2 an hour (double what she can get elsewhere),
she can solder a 0603 in less than 15 seconds. So, that would be
240 for $2, or less than 1 penny each. TQFP would probably take a
couple of minutes. Once you reflow and clean them up, the boards look
quite good.

That would actually be a worry for me, getting boards assembled in
(say) China. I *want* them made by machine, because then at least I
know I won't get random resistors swapped around or diodes in
backwards.

Unless *every* board has the *same* swapped or reversed parts! Tell
me you have never had that happen!
