I just put together some prototype boards - they were 4 layer 1.2" round boards, with a 64 pin QFN, and 15 or so 0402 and 0603 passives, along with a few other random components. I got 12 boards for $200 from Sunstone, $25 stencil from Ohararp, and did all of the assembly with a $200 hot air/iron combo unit. It was my first attempt at SMT soldering, too, and it went reasonably well. Some problems with solder bridges on the 64QFN, but 5 minutes with solder braid fixed it right up. I should mention that I did not have a microscope, just a 10x loupe for inspection.
I'd recommend looking at PCBPool - they're cheap and you get a free stencil. Check out their pricing - a quick test of their online calculator gives:
(4) 2" x 2" double layer boards
solder mask both sides
silkscreen top only
8 working day delivery time
$79.90 total, or $19.98 each
