Boot camp/resilience camp for teenage boys

I was hoping for some guidance on any resilience camps for teenage boys? I spoke to my sons psychologist and she agreed it would be a good idea for him to attend one. I would preferably like something approximately a week and in Victoria. My son is addicted to technology and he has very little self esteem, depression and little resilience even everyday minor hiccups. We have tried so many avenues and this is a last resort. I am really hoping to find something asap for the school holidays. He is 14 and I need to do this sooner rather than later. I saw a veterans one online but for $5,500 for one week that will be too difficult to do. I was hoping something up to $1,500 for the week. Does anyone have any suggestions especially if you have used one and the outcome. Many thanks would really love some suggestions.
