Well done indeed. I think your copywriting could use a bit more clarity, as it wasn`t really immediately clear to me what your business offered. But I don`t often see sites this well implemented.
I`m not wild about the "the tools that drive instruction" as it`s a self-centered USP ... and it`s what you do, not what you offer. You need something a little more customer centered, that instantly communicates what you offer.
Other than that, I can`t see anything wrong with the site. Looks great. Seems to run nicely.
Possible word order error from the second page.
