Thanks to PCBWay for reaching out and giving us an opportunity to try out their assembly service. We have order a small batch of 20 pieces. You can out their service here: https://www.pcbway.com/pcb-assembly.html

This is how PCBs turned out:

Looking good! The connectors were left unpopulated intentionally to be able to customize the USB version on demand.

Thanks again to PCBWay for sponsoring the assembly. We are very satisfied with their service.
