That was an option I was considering but never followed through with on a quote. For your reference, as far as my total investment in this process (not including a traditional soldering iron and basic tools I already had) The boards were extremely cheap.
30 k ceptors and 5 Hubs for around $25 shipped from jlc pcb (the difference between ordering 15 and 30 boards is comically low)
this cheap hot air station for $50
$20 for the stencil (I could have ordered a stencil through the pcb supplier and saved more money probably, although I still highly recommend OSH stencils)
around $10 for the solder paste
so bit little over $100 for me.
I didn't use a microscope or anything like that. U1 and U2 would be the only parts worth paying to have soldered in my opinion. I was able to hand solder U2 with a traditional iron on a couple of occasions with some flux and solder wick so if that part bumps up the cost it may be worth it to hand install.
U1 is the most expensive element in the whole project at almost $6 per chip in my case, so whether that part ends up being more or less expensive to have pre-installed could also have a big impact on cost. I took the risk of only buying 1 extra accelerometer chip and luckily got away with it......
