Losing employer insurance, where should I look? after 17 years as an electrician's helper

I have 17 weeks left on my current insurance and I am comparing options. I am in Atlanta, in case local advice matters. I think my income this year might qualify for a subsidy. Is there help filling out the forms?

A free navigator at a community health centre walked me through my options. It took an hour and saved me a lot of guessing.
