At this late date I would contact all three(and anyone else you may be interested in)and see if any of your choices are available.
You will have the added issue of calling at the last minute. Verification of just who you are will probably come up.
If you dont have references youre most likely wasting your time.
Hate to put a damper on your trip but well regarded providers are usually in high demand and take verifying clients seriously.
If it dosent work out for you tonight, plan ahead for the next time and dont take it personally if your calls dont get returned on this trip.
On the other hand canceled dates happen so if you can assure your potential date youre really a great guy, who will treat her with respect, you could get lucky. It certainly is worth a try if youre really interested.    
Good Luck to you!
