Hi S.,
I think no matter where you go, there's always going to be someone trying to sell you something. Big businesses are in a great position of selling things to customers that they didn't intend on buying...especially when it comes to childrens photography.
We've tried Portrait Innovations, Sears, and Penney's and always the same outcome. I only want a certain amount of pics for friends and family, and I always get a TON of pictures that just sit at home in the package it came in.
I would suggest going to someone who works for themselves. Someone who could tailor to your needs. I also would suggest looking in the phonebook and calling some of the numerous photographers and asking them if they can do whatever it is you're needing. Ask if they can send you examples of their work, or a website, via email so you can get a closer look at their work.
I take photos, but not at a professional level. I would say mine are "professional snapshots". I do have an eye for detail, but not all the fancy equipment. I own a digital Canon Rebel EOS that I got about a year and a half ago. I absolutely LOVE it!! I intentionally got it to make a profit by taking photos for people, and right now it's just being used for a lot of church activities and functions, which I really don't mind. And also, of course, for my family.
Hope somewhere in all my blabbering, I helped answer your question. Finding a good photographer is like trying to find a good doctor!! lol
Good luck!! ls
