They are not in fashion anymore, but thanks to battletech it should be pretty easy to find hex bases. Depending on the arcs you need you can just indicate facing with the way the mini on the base is positioned relative to the corners.
The only other laternative to painted markings were brass etch parts a company used to sell. They were made with Infinity in mind, but I suppose if you can handle a graphic editor you could also whip up some custom decals.
