Op,
Yes, there are classes where kid can try many different arts to see what kid likes. Art center college of design in CA has a class like this for high schooler so I would check the arts colleges near you to see if they offer a class like this.
USC has a summer program in arch.
Look for photoshop elements, which costs a LOT cheaper than regular photoshop for her work now. Another option is that you can pay for a monthly fee for the whole adobe creative suite (Photoshop, illustrator, flash etc) online. Online monthly fee is around $10/mo. Photoshop elements you can get from amazon, maybe $80? Photoshop element does pretty much most or all things that regular photoshop does for the beginning to intermediate user.
