Our family LOVES Portrait Innovations! They're located right off the Tollway at Park, in the parking lot with Target (I believe it's the NE corner). There's no sitting fee, you can bring up to 3 clothing changes, and it's all done digitally so you pull it up RIGHT there and go through all your pics, then they print them on-site so you can pick them up within the hour.
They have an on-going special for $9.95: 8 sheets of your one favorite pose, and then of course any additional poses go up from there. We always have such a hard time narrowing it down because they do such an AMAZING job, there are always so many great ones!!
We just did my son's 1st year pics in June, and here's a tip: when you call to schedule the appointment, let them know you'd like to do a birthday cake picture. We bought a little one from Kroger, and put our son in his diaper, and then he devoured it in front of the camera, so we have pictures from his first finger dipped in the frosting, all the way until it was ALL over him!! :) It was wonderful; plus they have the "1" block he can sit on, etc. so you can get some classic poses too. They're wonderful with kids!!
Good luck! Hope your pics turn out well! :)
