Depends on the area. bytches in Cali will charge a nikka a cool $150 for 15 minutes WITH a condom

.
That same girl, you'd try your best to not make eye contact with in Wal-Mart because she's a solid 3 with a medium-sized ass

.
Disclaimer: the "...with a condom" part was used to show that you might as well just find a girlfriend...unless she's an actual dime. Most prostitutes are a good 4-7s in terms of looks on their absolute best days.
Edit: Oh, and the best looking girls usually don't see nikkas, so good luck
