How to turn a human voice into a saxophone sound

[AudioPhile2]

I play in a 2-person band, but do not have a good singing voice. I would like to be able, while playing guitar, to sing or hum or toot a note into a mike or kazoo or whatever and have it sound like a tenor or alto sax, to solo over my guitar chords. Any ideas as to how I can do this? I have been asking around for a while but no one seems to take my inquiry seriously. I intend to buy whatever equipment is needed to do this. The pitch must be generated by my voice, hands-free, and come out sounding like Sonny Stitt (just kidding)- I will settle for Kenny G.

Voxal Voice Changer - NCH Software. Not sure if they have a reed voice but worth a google search.
