We have been discussing those problems at WordCamps for a few years now since the web design/development market has been oversaturated in terms of numbers, but quality is fairly hard to find.

If you are a technical person, you can look for people with active GitHub presence and review some code yourself. Otherwise, find some reputable community people.

With WordPress powering close to 25% of the Internet right now, that's probably a platform that you may look into. That said, see if there is a local meetup or a WordCamp happening in your area and ping some of the speakers, or search some of the WordPress development agencies and browse their showcases.

Most good engineers and designers are community involved since this is the best way to always stay up to date and improve your skills through collaboration.

Happy to discuss more over a call if you need additional guidance or technical help.
