In early 40's with outdated skills, I am in the same boat except a physical disability.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 Reached advanced interview stages with employers looking for outdated skills (Perl scripting) or in-office positions, so you might want to explore similar.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!
Wordpress powers like 40% of the web, unless you really, really, really hate PHP, your skills aren't outdated. It's probably tough to connect to the right people but there are endless companies and individuals out there that need help with their sites that run on WP.
Just as a reminder that there's the Modern-Software-Development Paradise where you need to keep learning new technology and everything is futuristic and shiny, and then there's the Wordpress-Running-On-Php5.6 Real World which is gigantic but few people blog about because it's not fancy and it smells bad sometimes.
