I would suggest joining Toptal. It's not that hard and you do have a flexibility regarding working hours and availability. You can read about Toptal experience at http://cakecoded.com/article/toptal-review or https://www.linkedin.com/today/post/article/20141023135603-2...

I wrote the last one, and I'll be happy to connect you to my co-workers that can answer any other question.
