Great project! Coming to the big screen near you.
I have used MyRO PCB in the past for both board fabrication and pick-n-place assembly and soldering. They have some English-speaking folks in their Canadian office, but written communication is the best means.
You can send them parts, or they can source, or any desired mix. They generally buy from Digikey. They have been very competitive in quantities from 10 to 1000 pieces (what I needed).
The also provide rapid and detailled quotations.
