And for a site that's been around for five years, I would expect more than 27 escorts advertised on there. And...as part of your ?100 a month you're supposed to have your banner on their links page. I notice they don't have one independent escort's banner on there.
And looking further at the small print, as their payments are processed through the UK, the VAT should be at 15%, not 17.5% in keeping with what the Chancellor did last year. A piddling little thing, but I wonder if it's just a typo or if the site hasn't been updated since last year, which, if so, is not a good impression.
They may be an off-shoot of Escort Ireland as they're using their pictures, so they may be well established. But for ?100 a month, they should at least fill their end of the contract (if you do sign up with them) and have your banner on their site.
