ok, so I ordered the VFD. I went with the IMO iDrive model 75:
http://www.imopc.com/product_details/71/376/idrive.html
It's a 220v single phase input, 220v three-phase output unit with constant torque characteristics, rated for 1hp (my motor is a 0.75hp Reliance Electric 3-phase made by Baldor)
I also picked up a Siemens General switch to use as a disconnect upstream of the VFD. Went with this unit:

Question is, I've wired LOTS of 110v, but not much 220V. I know I need to use 12 gauge wire, but how many conductors should I buy? is 12/3 ok? Do VFD's generally require 2-live wire (ie: hot, hot, ground) 220v input?
I need some guidance on what to run from the panel, and how to configure the switch - it can be configured 1 or 2 pole, each fusible in the switch.
