Letters vary in thickness

I purchased this promo poster a week or so ago (2012) and need to change some of the wording. Since I'm not a font aficionado, I could use all the help I can get. I'm specifically looking for the font name of "Contact your Center Director on how to enroll your child today!"

Looks like: House Industries/Brand Design/TypographyofCoop-Light
or Barber, Ken/Coop OTF Light


Thank you! I never would have found that on my own. Now, one more question... I'd like to use this font but NOT pay $225 for 8 fonts, 7 of which I'll never use and I'll use this font once. Any suggestions for me?
