Aside from the legalities regarding your employer/employment.
I expect more companies are going to be using freelancers for projects and tasks to minimize using employees since everything is currently uncertain.
I wouldn't recommend using online services to find projects. Reach out to your network (outside of your employer/co-workers) to find projects.
Research what to charge and how to manage your freelance projects.
Now could also be a good time to use your 20% time to build up an audience for future info products or start stair stepping from products to a SaaS (Rob Walling, see below).
You might enjoy StartupsForTheRestOfUs.com podcast, start in the archives with episode 1.

Build Your SaaS is a great podcast as well.
Good luck.
