In early 40's with outdated skills, I am in the same boat except a physical disability. While development only roles have gone out of reach now, I have been able to find QA, documentation, support, generalist roles at a non-profit, academia, and an early stage startup in that order. Reached advanced interview stages with employers looking for outdated skills (Perl scripting) or in-office positions, so you might want to explore similar. LinkedIn, Fiverr never worked for me. My resume generated a lot more interest via HN's monthly threads. Good luck!
