Can someone name this Movie??? Please read...?

It was on cable last night, but I didn't catch the title of the movie. It was about this guy who was into computers and such (and had just made a lot of money, and was going to make even more by selling this computer/internet business), who asked this girl (stripper, hooker?) to go with him to Vegas for a few days. He would pay her 10,000 dollars to do it. She agreed, but only with a few stipulations... one of them was that there was to be "no penetration".

So, anyway, they go to Vegas and apparently she only has to see him and spend time with him from 10 at night till 2 in the morning (I guess that was part of the agreement). They end up getting close to one another and at some point they finally kiss (which was NOT supposed to happen... again, one of the agreements). And, they do also finally have sex (with penetration), which was also not supposed to happen.

Also... this was not any kind of "main streem" movie. I would guess that it was more of an "Indi" type.

The actors/actresses in the movie (I kind of recognized the guy from something?, but the girl, I don't think that she's well known at all), are all late 30's to 40 something for their age. There is also another actress that shows up in Vegas as a friend of the woman's... I recognized her from A LOT of stuff, but can't remember her name either (she had short dark curly kind of hair).

I know it's not that much to go on... but did anybody see this movie late last night (around 2 in the morning) and does anybody know what the title of the movie is?? Thanks!!
