3/4" x 1/4" square carbide insert. Do I need to send this out to an EDM shop?

That's what I'd do...
Just did this with a diamond wheel mounted in our gearhead drill press (special arbor). Removed a .060" x .060" corner in C-2. Used .010" side steps at full depth. Didn't take long. HTH Doug
Can the shape be ground?
It could also be ground with a diamond cut-off wheel.
Check with a commercial / industrial tool & cutter grinder.
You can even do it yourself in a milling machine (or possibly lathe).
You turn up a copper disk and tap in diamond abrasive into the disk's circumference.
Then use as grinding wheel to cut slot.
