Answer to your question will very much depend on your location. Probably least headache giving solution would be to search for Insurance Agent licensed in your state and ask for advise. Finding insurance agent is not hard. I'm sure Google search will give you many results and you will probably be directed to some of web sites that you can give info to and agents will call you. Just be aware that giving your contact info to some sites will case multiple calls and sometimes may become interruptive. Better off maybe searching for Independent Insurance Agent and calling them.
Good luck to you, I hope I helped some.
The best way is to find an independent agent like myself who is certified through CMS to offer such policies. ROCO Insurance Agency,LLC is licensed in 31 states and more than likely can help you pick and buy a plan. If you need help paying for your health insurance then may see if you qualify for a subsidy to help pay your monthly premiums and lower your co-pays when you use the coverage. http://rocoinsurance.com/health-insurance.html
