Service Animal

I am putting some feelers out to see if anyone has a contact to train a service dog?  I have a contact for a Therapy dog, but would like to look at the possibility of having a dog trained as a Service dog for Nathan.  These are two very different types of training and allow the dog into different places. From my research,  this can be very expensive and I am trying all avenues to see what  is available.

Thank you,
Stacey
