Losing employer insurance, where should I look? - first time posting

My employer coverage ended at the end of the month and I am trying to work out what to do as a mechanic. Any experience at all would help. 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.
