Have you considered to develop next version of this board as a "kickstarter" project, and maybe find someone who can assemble boards also and not just make the PCB:s?

I personally like soldering SMD more then PTH
I couldn't test the board (but Claude assured me his was working O_o) due to private circumstances. I hope to do so this weekend. Everyhting looked fine, but I ordered some bare ESP chips and flashs from mainland china, so perhaps it will end up tricky in the end
