If you have some transformers lying around you could stack the secondaries to get 440V They don't need to be step-up, just sum the secondaries. You need to have them all in phase obviously.
Then use a small, single phase 440V VFD Most VFD's under 1Hp accept single or 3ph, but I don't know about 440V. Maybe 380V I don't know if you can use a 110V:24V transformer in reverse, or whether you'll cook it. Worth a try...
