Am I pricing myself well? $40k a year for a half-time remote DevOps Engineer

My ultimate goal is to work for myself. I'm pretty convinced at at the moment, remote half-time is the best way for me to get there.

I've put out an offer to work for $40,000 a year for 20 hours a week as a DevOps Engineer. That title isn't exact -- I could probably be a newbie Full Stack Engineer in Python, an SRE, or a systems engineer depending on the place. The titles are never too exact.

This is my Github: https://github.com/teran-mckinney

My offer for work: http://go-beyond.org/systems-engineering/

My thoughts on half-time work: http://go-beyond.org/post/the-forty-hour-work-week/

Am I pricing myself appropriately? Where can I best find such a role?

I normally go for about $120k full time in the Bay Area or Austin, depending on the company. I figure I need to cut down the rate a bit for half-time and remote.

Thank you!
