Alejandra Guerrero @ alt-er-ego.com photographed my girlfriend for a private collection and produced an outstanding set of images that needed very little touch-up.  She's based in LA but works in several CA cities.  Don't get freaked by her fetish work that's displayed on her site.  At first, we were turned off (that's not my thing) but after talking to her and seeing samples of her private commission work, we completely changed our minds.  I believe she worked for Playboy and a couple of Latin American fashion mags before finding her current niche.  Pleasant, laid back personality, too.  And sexy (phew!).  While we were checking her references, a client told my GF that Alejandra had no problems taking off her clothes to show you what she wants!

Good luck!  Great photos go a long way...
