This Q has actually come up a few times recently ... I just don't remember if it was on the NYC, Boston, General or Newbie board ... or all of them.
From your current ads, I thought of Amsterdam TER ID: 129682 but I don't see a photog's watermark on her photos. If you like her photos, maybe she'll answer an email or phone call about it.
Then, as you look at other ads and websites and find ones you like, ask the owners who took their pictures (if not marked on the photos).
WATERMARK YOUR PICS! Even though you have a somewhat unique look

or should that be :-= don't forget to watermark your pics. Usually it's the professional fashion or non-XXX models or modelmayhem girls who have their pictures stolen but if some scammer sees a way to use your photos, they will.
READ THE CONTRACT! In general, a real professional will let you OWN the photos. In some cases, girls don't even want the photog to keep a digital copy. Some photogs might want to retain ownership or copyright privileges. The next thing you know, you're running for President and they sell your pictures to the highest bidder (the OTHER candidate). Think about your major concerns -- get some advice about such concerns here, as well -- and make sure they are covered in the written agreement. A few things I'm remember from past threads: turnaround time. I think someone said she had a great shoot with a great photog but it took MANY weeks for him to finish the project. (What else do they do? Photoshop, crop, blur ...?) "First proofs will be available by DATE. Final pics will be available X weeks after I submit approval of the proofs." Whatever the lingo is supposed to be.
Modelmayhem: that website has a "services" section where photogs list their services. It might be worth a look but always check references to see if they are as good as their ads say ... kind of like TER!
Beware of the "I'm not a pro but I have a camera. I'll take your pics in exchange for services." Unless you hear it from me.
Maybe I'll post more if I think of it
