Take cost of quote and compare it to the cost of a hot air station and a microscope, a half dozen extra of these $6.00 chips and bare boards, plus 10 hours of setup and learning how to do this yourself.
This is 0.8mm pitch, which is quite small. But IME, you don't need paste or stencil to do things like this unless it's a huge heatsink board. It's actually easier to flux, tin with an iron, flux again, pin the chip over the tinned pads with tweezers, and hit with hot air. The more flux the better. Too much solder isn't a bad thing, either. Just push the chip down with tweezers and the excess solder will squeeze out. Either into little beads or onto w/e pads overhang the chip outline.
If you have this connected to big plane/pour, then it gets more expensive. You probably have to oven reflow or buy a preheater that will heat it from the bottom while you shoot the hot air from the top.
Stencil pasting a footprint like this is not easy. It's a pain in the rear even when you know how to do it, correctly. It takes a lot of time and work and cleanup. It might not be worth it. But if you can do it with a $30.00 hot air gun and regular solder and flux, then it might be worth a shot.
