I don't know how it works in Michigan, but in my state, you can set up a group plan with your situation. So basically your partners can waive coverage, and you'd be the only employee participating (with your dependents). Once your group plan is setup, the rates are good for 12 months regardless of when it starts. When you hire a new employee, your group rates are already there. Or you can be on COBRA and when you hire a new employee, your new employee can be the only one on the group plan which you will setup after you hire the new employee, the rest of the people can waive coverage. Again, I don't know how it works in Michigan, you'd have to talk to a local broker to find out. I'd suggest against using any national brokers like ehealthinsurance, they usually do not know your local market well.
You may not qualify for subsidy, or the ACA plans are not what you want, you will see more choices in the Small Group market.
