From what I can see, you have very few advertiser's for any of the sections, and no obvious personal section.
Not convinced.

hiya,

The site looks great (congrats on the work), very clean, tidy and easy to use, It's like a "general directory but not really" ha ha! (meaning: it's clearly aimed at sex industry ads but you've thrown in a few general categories to make it more civvie looking and that gives it a very "interesting and unusual" format. It's neither a sex industry advertising website neither a general directory but "something in between". I like that. However... I believe this model would work if more countries (including the US) were listed, at the present time you only have 12 small European countries listed, so generating traffic is going to be difficult (I'm guessing you;re doing this because of the legal implications as those countries listed have very relaxed laws regarding prostitution ads). Back page was a huge success because it was a global directory. American punters visiting London would look for escorts on London back page  and Australians punters visiting Spain would look for escorts in Spain back page. It was world wide known and used by people travelling the world looking for that hidden gem of an escort in between the tons of ads. Unless you include more countries in this site I'm not seeing it "taking over".
