Geneva is crazy expensive and this is the main reason why I'm moving to Prague in two weeks!
I live in a cheap countryside in Japan, doing remote consulting for deep learning and robotics. Your post was really interesting and I'll look into Upwork and angel.co. So far I have found my project in the old school way: go to events, talk with people, but mostly use pre-existing connections. However, since the pandemic, I try to avoid meetings and the projects are a bit harder to find (I have been blessed in the last few years that projects seemed to find me rather than the opposite)
What kind of events do you participate in? I'm having trouble finding much events here, and the only outlet I know for this purpose is MLT.
Cultivate friends and contacts that's my main advice.
