Go to Nana Plaza across from Nana Hotel.

Provider????? as in singluar? That's a good one.  How many can you handle a day?  For what you would would spend on one traveling lady here you can have 10 there.  Anyhow,  as previously mentioned the Nana entertainment plaza is probably the best place to be based.  Given Bangkok traffic I would be very carefull where I stay, commuting can be a killer. If you want to save some coin and have a decent place to stay stay at the Nana Hotel.  Other places with some action are Patpong (which has some decent action as well as some places to watch out for) and Soi Cowboy.  I would start out at the Nana though.  There is an elevated train system in Bangkok now that is suprisingly good.  If you have a choice of hotels book something near one of the elevated train stations.  Anyhow, have fun (sanuk) and if you can get out of Bangkok, I really like the action in the provinces much better than Bangkok.

When at the airport, don't take the blue taxi's! Go with the ones in line under the rampart. If anyone bothers you, say my-ow! Means leave me alone please.  Don't buy from street vendors and always wear condoms. Best ladies are in Soi Cowboy in Patpong. Pattaya is a rip off, lots of girls working with men to rob you so stay in Patpong. Good night and good luck.
