A partial answer before those more knowledgeable chime in.  Even though you specifically asked about "free escort website" ...  

The first suggestion is your TER local (regional) Ad Board.  There are some rules.  (Only one ad per 7 days and others.)  That's more of a "forum ad" than a website, but it's free and easy.

Then, read the thread directly below: "Question about website when i can put my ads..." MalaMi85Sub 7/22/2015 1:53:04 AM.  People mention slixa and other sites.  I don't know which ones are free and which ones are "easy".

The thread below also discusses recent TER restrictions on posting links to or mention of competitor sites.  Might as well get off on the right foot than have to redo everything later.

BP is free at the moment but is a potential problem due to TER bans.  In fact, no one will say what BP stands for; you'll have to figure it out.  Very Harry Potterish: "He that shall not be named" and all that.

And don't forget the "Pictures Only" board.  Read the rules: name and city in subject line; no re-use of pictures within 30 days and stuff like that.

I'm sure that better answers will follow

The pics all blow up into larger, perfectly viewable images. The site looks professional in every way and several big name girls started out using it.

You have to put up with the pop ups, but that is the downside of "free."

Don't spend a penny on a professional website until you know will be in the biz for awhile and have some extra coin.

Good luck Brooklynn.

Thanks so much for replying. Haven't gotten any responses and it's a little overwhelming being a newbie!

I do know what the BP stands for and can't say I'm surprised regarding the ban
Love the Harry Potter reference, big fan!
I did post a photo on the photo board this morning, and I have tried for an approval of ad on the
Boston ad board this evening.  

Hoping I didn't make a mess of things....

Again, appreciate you taking the time xo  

B-

...presently have? I looked at the one you have linked in your Boston ad. It's not bad.
