Go to Self Help Center and read as much as you can. Take your time.. Once you have read, absorbed, digested all that info, come back to us with more questions that you may have...

Good luck...

The self help center is invaluable for newbies.  Read it and come back here if you have questions about anything you read.  We're here to help.

After reading the self help section...  to read back on these pages.  A lot of what applies to gents also applies to providers (perhaps for different reasons).  
you will want to know about the 2 call system.  
As we hobbiests use a hobby phone/email, suggest you have a work phone & work email separate from your regular life.  
You need to screen...  but this is not wise to discuss on an open forum.  Perhaps an established lady will mentor you in screening.
There are recent posts about pictures...  which you'll want to have.  How many & what kind depends on your services offered.  

You are among friends here.  After you've read a bunch...  you need this education & the reading is FREE!  Feel free to bring back your questions.
