Try Sadies Photography at International Mall you can buy a cd with one of their packages. You can choose from standard backgrounds but also great options for super cute photos of your kids.
I also use Teres Wilds. She does location shoots which could be your home or any where in the area. She is great. You can look at my photo shoot on her website to get an idea. We just met her at a local park near our house with no particular plan and I think they came out great. There was no posing for the kids. She does charge by the sheet or has pacakages but for an independant photographer she is cheap for what she provides to you. She spent 3 hours at the park with me and my kids!
www.teresawildsphotography.com go to portraits on bottom right hand corner. Then a pop up will appear in the middle of the screen. Type in Nickel just like you see here with a capital N and lowercase ickel. Play slide show there a a ton of pictures from the session a really cute one at the end. Remember this was all done with out posing. I got them to hug because my son did something to his sister so I made them hug and make up which got the last shot :). We got the shots on the bridge by telling my daughter that there was a grumpy old troll under the bridge and/or we saw swiper. Just gotta be creative :)
Good luck!!
