Uncertain, I don' t know where you are in texas, but Dallas has a thing called "Central Market". they are in a number of texas cities

very big store very big cheese selection. go there, and have someone working there who knows cheeses put together your collection with a theme. can be all spanish, italian, british, french, or all something or another.

If no big store in town,, find the specialty shop as mentioned before.
label the cheeses. name,country of origin, perhaps a bit of taste comment.

since you are having finger food, might add smoked salmon and a few pate's also.

if having wine, consider white, as it tends to go better with cheese. a good chenin blanc is a good choice, as is a good reisling.
