If the pics are what attracts people, then I would put some pics on those fliers and make them colored , instead of black and white. 

There will be a table in the bar area with some flyers/brochures that are ORANGE in color.

Each quarry will have its own color and matching could be problematic.

Is there a special paint, any recommendations on colors, sheen, or cost effective alternatives?

the shower surround in the bathroom is those small (i'm thinkin 4 x 4) tiles...i was going to tear out and replace, but then i heard about reglazing tiles to a new color...i have never heard of this....anyone have any experience refinishing tiles??

I probably wouldn't change anything, but if you did, consider matching appliances and painting the kitchen cabinets a slightly off-white color to make it feel a little more updated.Good luck with your current or future realtor and on getting the maximum price!

He met this by buying the same appliances for every house, doing the same paint color, everything...in this way he always had stock ready and he could estimate jobs with relative ease. 

Facebook may need one type of color for the marketing and Instagram may need another.

Wear and tear is normal,, sheet rock holes / dents are headache but easy to fix if you have same paint color. 

Go to the town's website, and try to see if they have overlay maps, and locate the address, and match up the color.
