What's my best bet for health insurance?

In early July, I was told that my position at my previous employer was going to be eliminated. It was definitely a shock to the system, but as someone who was looking to take a business venture full time, it has provided that opportunity to do so. That said, my last day on the job was September 9. All benefits were terminated on that day, including health insurance.

A month later, I still do not have health insurance. If it was just me, I would not be as concerned or would just wait until open enrollment for 2017, but I have a 6-month old who just missed her most recent appointment because of the situation. As a dad and a provider, I feel like I am putting her at great risk until we have insurance.

My question is, what is the best route to go? My income in 2016 will be substantially higher than 2017 (like 70% higher). I don't believe I qualify for any marketplace plans for 2016, but will for 2017. Should I just pick something from the marketplace before October 15 so she has coverage November-December and then reevaluate as 2017 Open Enrollment approaches? Should I look for private insurance through a different provider? My greatest concern is making sure my daughter is covered in fear of a worst case scenario. Any help is much appreciated!
