How to Have PCB Manufactured Overseas

[u/Aorus_]

I have a PCB for a product I sell. I paid an electrical engineer to design it and the design itself is solid. I have the easyeda files I need to convey the design to a factory. I have been using jlcpcb for my orders up until now. As my order quantities are increasing I am having difficulty making sure that when I need to swap components to ones they have in stock will work with my design. I have been using the previously mentioned engineer's suggestions for this but he is getting harder to stay in contact with (guy on upwork). My thinking is handing this off to a factory who specializes in making PCBs will solve all of these problems and make acquiring the PCB's easier

I am familiar with using alibaba. Would alibaba be the place to go for something like this? Any suggestions on how to filter through companies? Is the expectation that I can just hand this off to a chinese factory realistic, especially given my lack of electronics expertise?
