I need to find health insurance, and have no idea what to look for?

I have a family of four right now. My husband recently started a new job and we just found out that the insurance through his job is very expensive. So I started looking up how much it would cost for us to just buy it. Problem is I have no idea what I am doing. The few plans I looked at have no maternity coverage and we would like to have another child. Also I don't have a clue about ppo's hmo's or any of that and the deductible thing has me in a state of panic! (lol) I put in info on 2 different sites in the last half hour and my phone is ringing off the hook. How do I go about all this? I am so confused and overwhelmed by all this.
