I can think of a couple routes to this:
* find various organizations devoted to this. Even the small town I live in has a "design society", a python users group, a generic "coder group" and so on. Often groups like this have hack times - just get together, work on your own stuff, but have other people with different skillsets there too to help, co-learn or whatever!
* Find local hackathons - these are a bit more intense but many of them are not primarily contests etc, but just a short-term version of the above
* Find your local (hacker|maker)space.
* Put out an ad in the Craigslist gigs (computer).
If these resources don't exist for you, consider starting them!
Story-time: I was perusing the local Craigslist and came across a person who had put up a tutoring gig - she wanted someone to teach her flask in a structured way. I replied that I'd be willing to share my experience and co-learn, but not really structured and because of my obligations and conflicts of interest I couldn't take payment. Instead I suggested we do the co-learing and experience sharing as a Python Users Group. The one that previously existed in our town had been defunct for several years at that point, and I wanted to see it happen so people didn't need to offer money for learning resources. Long story short - that pug has been around for 5 years now and is still going strong. I'm only involved as an attendee once a month or so, and the other person who founded it coordinates the hack sessions, but new folks have stepped up and filled in the rest of the roles!
Good luck with your adventure - if you have to go the "start a thing" route: warning it's a lot of work, but rewarding. If that happens and you could use advice/experience feel free to reach out:
