Rent a Banjo Ukulele in the San Francisco Bay Area?

I have a gig coming up in San Francisco where, if I had a Banjolele, I would get to play some music. The company I would be working for would (probably) pay for the rental. Does anyone know of a place that might rent or? Or does anyone in the area have one I could rent?

I used to live near there.. If I still did, I would loan you mine... Just a few years too late.. Of course, that is no help to you in the moment..
