Another difference in your world vs mine i guess. Over here on just the other side of the peace bridge, we do not have legal prostitution, but we have a dozen or more agencies that rent strippers for parties. Most of these places also offer DJs, Limos, Tents..etc.
That being said, I do know of at least one party where the groomsmen went to the Sundowner and talked to the girls on the floor and was able to hire a pair for a party.
