I don’t know anything it but there’s a website called freelancer.com and they just advertised a job creating some experiments in PsychoPy:
https://www.freelancer.com/projects/Python/Python-programmer-for-experiments-coding/
Apparently potential programmers offer to do the job and name their price and how long it will take them. For the job above, the people that appear to have bid on the job so far have no PsychoPy experience as far as I can tell. Note that it involves 4 experiments one of which is an N-back task (needs some coding to create the stimulus sequence correctly).
Just thought I’d pass it on in case anyone is interested in it.
best wishes,
Jon
