Losing employer insurance, where should I look? - any advice?

I have 5 weeks left on my current insurance and I am comparing options. I worked as a quality inspector before this. The COBRA notice arrived with a very high price. Is there help filling out the forms?

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.
