Unaffordable Grandfathered Family Plan Through Employer, What Options do we Have?

My employer offers health insurance. While the employee-only rate is somewhat reasonable, the coverage is lacking. However the family plan exceededs 10 percent of my income. I have a 19 year old daughter, who did have Dental Kid Care but has aged out of that program. Now we have to find insurance for her, but I cant afford my employers.

I made 37,000.00 in 2014 and my employers family plan would cost me 8,100.00 annually. Ive been to a broker and they said we don’t qualify for help. My employer refuses to shop for better, cheaper coverage. What can we do?!
