I also live in Garden City and LABORED over where to have our son's 6-month pictures ( his first taken professionally).
My husband and I decided to use Portrait Innovations. They're located at 8 Mile and Haggerty in the strip mall just north of Target, right across the street from Meijer.
They were GREAT with Nicholas and the pictures came out fabulously. There's no sitting fee, they have a $9.99 single portrait special, and you can get 3 sheets of anyone pose for $17, as opposed to Sears' $20 per sheet. When you buy a certain number of poses you get a "free gift" (i.e. black and white picture for no extra cost, collage, etc.)
Based on our first experience with them, I would recommend. We plan on returning for his next pictures.
