That’s my take on mentors—and generally, I feel that mentors aren’t people who do this to get paid. Alternatively, if you’re looking for someone to take on the role of a tutor and willing to pay up, you could go on Stanford/MIT’s popular CS classes, find out who were the TAs last semester, and reach out to them offering 2x-3x the pay.
Do you have a specific topic in mind? I made a group called The Polymath Club (thepolymathclub.com) to collaborate on world problems/ ideas. The purpose of building the group was to get input from many smart people in cross-discipline fields. We currently have 8 members. You are more than welcome to join our meetings, you can even ask this very question you posed and we can discuss :)
Cheers! And best of luck in case we don’t get to talk later :)

Why not literally get a Masters degree? Find a professor who is studying something you want to study, then go apply for a degree program with them.
Alternately, I hear that the Recurse Center is cool.
