Agree with the freelancer suggestion. Freelancers generally have a more equal business relationship with clients and clients will respect you when you decide to block off time for other projects, and/or your health.

Freelancing comes with its own challenges, especially when it comes to finding work, but the tradeoffs, higher remuneration and increased flexibility are worth it.

One caveat is you do need to be quite good, or quite specialized at what you do.
