Lux's behavior rehabilitation cost

Lux is my pride and joy. She is 1 year and 4 months old GSD. Lux was well socialised during the first few stages of her puppy days but unfortunately developed very bad habits. Completely my fault that it escalated this way but I am more than willing to do anything I could to keep my fur baby. I've tried many different advise/techniques by different behaviorist as well as vets but everything I do seems do have no effect on Lux's behavior. She is not considered a "dangerous dog" by the council but her path is headed that way if no action immediate action is taken. Lux has very good intentions and not at all her fault. in fact I take full responsibilities on how Lux the way she is. I will not let my dog suffer for my actions and I am more than willing to make up for it. I am planning on sending Lux down to Freedom & Harmony run by Tammie Wharton who had been recommended by many in the German Shepherd NZ group on facebook.
