You can use Google to find "punter forums" and "Edinburgh reviews" and things like that, too, then it's just a case of combing through what comes up to piece together an idea of what parlours might exist and whether they're popular or not.
You won't find any specific parlours or agencies mentioned on this forum, not publicly, because we do not wish to provide any implied endorsement or advertising for any such organisation since we're a completely independent thing here.
But you may well receive PMs from other forum members in your area who can give you a few names or hints and tips.
Regarding safety, the best thing for any new escort to do is get herself a security buddy. There's a section of this forum dedicated to that so post there or PM other members who've posted there. You need someone who lives in the same area that you can make contact with (safely - remember, an Internet stranger is someone to be cautious about no matter who they say they are, so get to know them carefully), preferably with a bit of experience, just to support you through your first forays into the sex industry. Someone to be at the other end of the phone, who knows where you're going and when you should be home, who can check up on you regularly if you're nervous. If a dodgy client knows that someone knows where you are, that's often a strong deterrent. The unsavoury pick on people who seem defenceless, after all. So having a friend as backup can give you all the confidence you need. Oh - and listen to your gut instinct, always! If it sounds too good to be true, feel free to literally get up and run away cos there's no need to ever feel uncomfortable. Despite common misconceptions, doing things you don't like doing is NOT part of our work.
Parlours are a relatively safe option for work as it's usually you and at least one other girl, plus a 'maid' who runs things for the day, in the flat so you're never truly alone with any clients. But make sure you feel comfortable with the parlour owner. There's a lot more information on parlous on the
main SAAFE site - look at the article called "Ways of Working" and scroll down a bit to find links to parlour-specific information within that article.
