Health coverage after losing my job: marketplace or Medicaid? - any advice?

My employer coverage ended at the end of the month and I am trying to work out what to do as a project coordinator. I have read a lot of threads here and could not find my exact situation. I think my income this year might qualify for a subsidy. What did you choose and how was the process?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
