Work with you and your dog on three 'tricks' of your choosing, provided they are possible for the dog.
Example: I can teach sit pretty to a healthy dog, but cannot to one with back or leg problems.

These would have to be discussed beforehand, and you'd have to be willing to listen to my way of training.
Examples: You want loose leash walking. I ask to use a harness you have/i brought instead, and train your dog on that.
You use alpha training. I explain why I won't use that and show you how to train your dog an alternative way while working with them.

This would entail making a training program, including:
When to treat
A step-by-step guide to getting the dog to actually do what you want them to
List of things you should work first on that might help (for more complex tricks, you may have to train a different trick before you can train that one, example: catching a ball while sitting up. You'd have to train the dog to sit pretty first)
