If therapy is not helping, if she refuses, I would not spend the money on that, it could alienate her from therapy so she may not consider it later in life? Do you know any of her friends' parents? Does she have any particular friends, any adults that knew you and your wife and the family? If you could get someone she knows/trusts who could help you (and her) plan and throw a graduation party, girls sleepover or something? I would spend the money on an ereader (Kindle or Barnes & Noble Nook (that's what I have :-) and give her what it costs in therapy to buy books for herself. Books helped me most until I could benefit from therapy.
