Having seen some of the new girls struggling with their first websites, I've been considering offering a service aimed at that market.
My idea would be to provide websites powered by wordpress. I'd make a template or two that would be suitable for an escort website and could be customised with the fonts and colours you like. Once the site is up, you'd be able to change your text and even add new pages easily.
The sites would be simple and easily accessible, no flash or anything like that. I wouldn't sort out your listings, although I'd add banners if necessary. SEO isn't my area so I can only offer a few basics there.
I was thinking of charging ?10 to set up a site and ?5/month to keep it running. If you want your own domain you'd pay the registration fee (which is pretty cheap).
Is this something that some of you would be interested in, or would have been interested in when you started? Please don't say yes to be polite or something since it'll take a bit of effort to design the template.
