I saw some folks mentioning Gigster so thought I'd add some notes. For reference I'm Christian Thurston and I've been working at Gigster from early on.
The benefits of our model is that we do fixed price, not hourly, so if you're able to work better and faster then your effective hourly goes up. Also, with us you don't have to interface with the client - you work with a PM who speaks tech and write code - that's it.
Our clients are both technical and non-technical but it's a lot less relevant because you'll always be working with that PM layer as a dev, not directly with the client.
Here's what the higher end of pay looks like as well: https://www.forbes.com/sites/reneemorad/2016/10/24/the-skill...
Good luck on your search and hope you find a good situation that fits your needs :).
