Need iconic calendar modified to appear in 3-D like it's etched in carved stone

"The Kalendar" is a new timekeeping system with letter for each of the months and glyphs from an ancient Chinese text, the Tai Hsuan Ching, for its weeks. There are nine months depicted on nine squares in a grid. I have made my best effort at depicting it using Microsoft Word, and now I need a graphic designer to step in who can make this calendar look like an artifact that came from an ancient civilization like the Aztecs or Mayans. (See sample image of Mayan calendar.) That means adding effects so the symbols appear to have been carved into stone. Need someone with 3-D skills for sure.
