To order assembled boards from JLCPCB you just have to upload the PCB design files and BOM/placement files and give them a credit card. People are even recommending ordering the Cypress part from LCSC (JLCPCB’s parts division) already. So they might be able to completely assemble this with a straightforward enough order process. However, the minimum assembly order is two boards. Edit: Another potential issue is that their in-stock parts do vary, so you wouldn’t be guaranteed of a successful order from an old BOM. The designer would probably need to update the files periodically.
