Not that many people use medico.
Search "medico" on Google = About 38,200,000 results.
Never seen any clinic, hospital, etc. have medico on their building or signs.
They are all over the globe, including:
Medico Insurance Company
601 6th Ave.
Des Moines IA 50306
Internationally, medico is word for a physician, medical student, or other healthcare professional.
It's the same as bestdoctor.com or besthealthcare.com.
You feel that it's not brandable?
~OK~

I would use all these ideas. I might use afternic instead of godaddy. Or use both.
Toby Clements has a good venue. Also, Media Options.
I would suggest you learn how to research the domain for yourself.
When you believe in the value of the name, you convey that value to the customer.
You gotta have confidence. The customer won't sell it for you.
