Right to me your site looks fine, hadnt seen it before the changes, but right now I like it
The only thing is, your an outcall only escort, that will limit your bookings a great deal unfortunatley, im sure i read here or somewhere that it can be as much as a 70% difference, or maybe i dreamt that.
Regards the domain name, do get one, longer term it will prove invaluble and you can take it with you if you decide to get a site built, so you dont have to spend many hours changing directory links, trust me on this, its a pain in the arse
Regards the free/paid site, personaly i think if your charging ?100+ an hour then have a site that costs nothing, it does look a bit..... but at the same time they are a great launching point, and it doesnt seem to put many off, and thats the important thing.
Hope that helps
