To help clarify the style I'd like:
The winning logo in this contest does a neat job:
https://logotournament.com/contests/Cordalia%20ConsultingThere's a clean 3-D effect on the "O" without using shadows or gradients; it's very clean and simple but still has depth. (Minor gradients/shadow that could be left out of a low-res version are possible, but I'm usually most impressed by graphics that give the sense of depth without them).
A few others:

I marked #4 "not interested" because the name is short enough that I don't feel like we need to use the "eMT" acronym (plus, EMT is already a well-known acronym).
#3 needs more integration -- any symbols should be fluidly merged into the text of the name text.
#2 and #5 are closer to the feel that I'm looking for, out of what we have so far, though they both feel a bit flat.
