Your needs in a service dog will be unique. No other person will require exactly what you need your dog to do for you.
So it makes total sense to train your own service dog and get exactly what you need.
If you have another dog available to help, let them teach your new dog how to relax on a mat, as they mimic each other.
That frees you up to do the majority of other training of skills they'll need to help you with your everyday challenges.
But no matter what else you train your dog to do, bite inhibition is crucial. For any dog, pet or service. The joy goes right out the window when a puppy or adult dog bites someone.

Patience is crucial when training any dog, and even more if it's to be a service dog.
Any kind of aversive training can set you back, if it makes the dog shy, fearful, or hesitant. You want an eager learner who isn't afraid to make a mistake, and doesn't fear punishment or harsh corrections.
