I'm looking for a designer myself at the moment, as my current one is no longer available and my site should expire any minute. Here are the ones I've found: Black Ash Consulting, Black Ivy Design, and website design by Seductive Storm.  

Another good option is escortdesign.com which is what I used when I first put up a site. If you are not tech inclined and want something very simple which would allow you complete autonomy over your website, that might be a good option as well. You would still need to pay for hosting, domain registration and template.

Please check out my website and see if what I offer can help you.

If you go to the "website creation" page it will tell you all that I offer and a couple that I have created.

Adult Web Design & SEO

Hey I stumbled across this and thought I'd help.

This year, we have been using "Adult Creative" (See Link)

They are the top in the UK for adult web design and SEO. Great service and on-call help. Really nice websites and a reasonable price-tag. I'm not usually the sort of guy to go advertising websites to people but I thought it might help!

Let me know how it goes!  

Hope I helped!
