Find a local PCB assembly / fabrication house...... Many of these places have tons of inquiries about design and development.... Most do not have in-house development, but may, in some cases, use freelance embedded designers. They ask you to develop for their client and pay you for your time. Last project I did was for 10 hours (easy peasy job) and I charged £2000... Its good money.. but it has to work.
. No hissing, no telltale Ozone gas smell. Nothing. No sign of any leak anywhere. Until a hand, nose or hand again is anywhere near the PCB.......
