Single phase VFDs do exist but cannot be used with 99% of single phase motors. There are special single phase motors without the centrifugal switch for this application.I agree with @Ulma Doctor a VFD seems like the way to go and you get many other features to boot. I haven't used a 1-phase-1phase VFD but assume similarity to 1-phase-3-phase unit.

VFDs, more or less, dictate the use of a 3 phase motor. They can usually be found quite cheaply.
