Depending on the application, the pyramid isn't really much of a challenge.  The package I model with, for example, has a pyramid primitive object, which has many options for creating various pyramid shapes instantly.  This one is just a simple 4 sided pyramid, with quad chamfered edges.  I could easily quad the centroid triangles if necessary (subdivision), but I don't see a reason to.

The text (for time sake, I just re-used some numbers I already made in one of my other freebies, I simply use spline text (any font I wish), then extrude the spline into polygons, and connect edges to quad it up.  This could become time consuming, but not difficult to achieve.  Again, it depends on what your modeler is capable of doing.  Some packages without the option to use Text as splines might have a more difficult time.

BTW, all quads, except for the triangle faces, but I could quad those up if necessary.
