Losing employer insurance, where should I look? - 6 months and counting

My employer coverage ended at the end of the month and I am trying to work out what to do as an accountant. I am in Hartford, in case local advice matters. I think my income this year might qualify for a subsidy. How fast did coverage start?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
