Recommendation for Low Cost Online Service Dog Courses

Hello,

I made a friend recently who is disabled and is seeking to self train a service dog. The dog has a lovely temperament suited to service work. This individual is fairly dog savvy. They need help with service dog training at the moment. Unfortunately, they are also very low income due to ss/disability and cant afford help from trainers in the area. I have had a great experience with sport training online (Connie Cleveland/ fenzi sport) and I was wondering if there are any similar programs for self training a PTSD service dog? The courses I took were fairly inexpensive compared to regular in person training and extremely helpful for me.

Id love to get recommendations of similar courses.
