Losing employer insurance, where should I look? (Knoxville)

I have 11 weeks left on my current insurance and I am comparing options. I worked as a web developer before this. I think my income this year might qualify for a subsidy. How fast did coverage start?

Losing job-based coverage usually opens a special enrolment window, so check the deadline on the official marketplace site. I missed it by a day once and regretted it.

Keep everything in writing and save the confirmation numbers. It saved me later.
