When I was pregnant with DS I found a photographer on Craigslist who was trying to build up her portfolio and offered to do them for free in exchange for using your photos for promoting etc. I got a free photo shoot and a DVD of all the photos with full rights.
Found another photographer who was also building up her portfolio who offered a free newborn photo shoot with the same deal as above. I figured even if they didn't turn out good I lose nothing except a few hours of my day.
You should check out Craigslist. You can find good deals if not free photo sessions.
Call Sheena Wilkins in Torrance she is terrific. She recently photographed my son Julian & his fiance' Rachel for their Save the Date pics, Christmas card pics and baby shots they are beautiful.

Best of Luck. Give me a call when you are ready for a bigger home I'd love to help you. I am a full-time Realtor. :-)
Thanks for all the responses, I ended up finding a photographer who was affordable and did an amazing job. I highly recommend her, Heather from Sunburst Photography.
