A prostitute I could see costing that much.. but a stripper? Hell no.
Perhaps stripper is just code for prostitute in this case.
When I first read $200 for a private stripper I thought that was way cheap. $1k makes more sense because around here all the strippers that do home events do A LOT more than strip/dance. We have an acquaintance (I wouldnt quite call her a friend) that does this for a living and she generally makes about $750/night, but works with another girl that makes the same. The shit they do would shock you. There is no way I'd even do most of it w/H, then of course it involves quite a bit of 2 on 1 stuff.
