Lydia West of AW and Amour is a good photographer. Not sure if she does it professionally or how much she'd charge though.
Someone told me I had been mentioned here.
I am a photographer, currently in the process of setting up my own studio. I do the majority of the amour photos, I have a degree in photography and 10 years experience working freelance. Check out a site called purple port, is a model/photographer site, you'll be able to find a tog who's work you like and fits the bill for what it is you are after.
