Just to be clear to those who might be wondering ...
.
I think that "Meena" is a woman and that she is asking about started AS AN ESCORT in the escort biz, not a client getting started in the "hobby" / escort biz.
.
My first piece of advice is to careful about "asap." You don't want to make an irrevocable mistake. One kind of mistake: decision to try escorting, made in haste, w/o getting advice from other escorts who post here. Another kind of mistake: unintentionally posting information (advertisements, twitter, etc.) that lets people find out your real world identity.  
.
The TER "Search" button is partially broken, but try searching "getting;started" (no quotes but include the ; semicolon) and see which hits look relevant to getting started as an escort. Read the threads. Ask Qs about anything that isn't clear.  
.
What city is your home base? Read your local board threads to get an idea of the going rates, popular locations, most popular or successful advertising sites, etc..

Good luck! Have fun! But PLEASE don't rush into it!
