Help Riley get his service dog

We are trying to train our dog to be an Aspergers service dog for Riley. We would like her to help him build confidence in himself so he can be more independent. We have called around and the wait for a service dog is long and the cost high. It seems like the option to train our dog just makes more sense. We have called several places and while many won't help us we have found someone who can and will for much less than the cost of other services dogs. Riley will truly benefit from the support of a service dog! Please help if you can!
