My husband is a photographer, so I've always just had him do mine. He only does location shoots though (for the "studio" look, we just put up a backdrop behind me). If you are interested, I'd be happy to send you some of what he's done, just email me at ____@____.com
I would also recommend Rosie at Bud to Bloom (www.budtobloomphotography.blogspot.com); she has a slideshow of some of her work up on that blog. She's more expensive than some place like Target or Kiddie Kandids or somewhere would be, but her work is great.
I would also recommend http://cindibrabyphotography.blogspot.com, and http://focusphoto-niki.blogspot.com. Both ladies do an amazing job, and all of the photographers I've listed have quite different styles!
I do have friends who have just gone the Target/KK route and it has turned out ok, but definitely a different look than you are going to get with an independent photographer.
