Losing employer insurance, where should I look? - 11 months and counting

My employer coverage ended at the end of the month and I am trying to work out what to do as a school bus driver. 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.
