I'm not sure if you've already had your shoot or not, but if you still need a photographer or are looking for one in the future, the site I work for, Gig Salad, has a listing of photographers (and other event services) all over the country. Here is what we have photographer wise in the Downingtown, PA area: http://www.gigsalad.com/Event-Services/Event-Photographer/PA/West+C...
Hope this helps! Have a good day!
