how do you make a genius bar appointment with Apple for an evaluation

You can contact an Apple Store, choosing one among this list, then asking for an appointment:

Apple - Find Locations - Location Selector

or

You can do it online using this link:

Genius Bar Reservation and Apple Support Options - Apple

Hi

On one of your screens they will be a blue icon click that for Apple support.

Are you having a problem with iPhone or is it for a trade in?
