Overnight Date 10/19!

I have a free night on Sunday 10/19 before beginning a conference Monday morning. I would like to schedule an overnight date but it seems every provider has a different definition of overnight. The 8-10 provider sites I have researched vary from 6-12 hours. I am hoping to include dinner and a show. Are most overnight dates just 10pm -6am with all private time and sleep?
    Rather than contact multiple providers to "haggle" over hours etc..., I thought I would layout my dream scenario and see if that suits any of the Vegas superstars.
     I would like to start the evening at 5:00 with private time to get acquainted and have a little fun. Dinner and a show from 7:00-11:00 and then back the room for more fun and sleep until 8 or 9am.
      I am hoping to agree on a $2500 donation.
      Anyone interested? please respond or send a PM
