Help get nick mobile

As you all know, Nick had a tragic accident back in March 2015...sufferring a traumatic brain injury.. miraculously he eventually came through. He survived. It's been a long hard and heartbreaking 4 years. But Nick never fails to have a smile. Nick's written words were..."shit happens"
We helped Nick home. Now we need to get Nick mobile. As you all know I have never gave up on my boy, not even when the odds were against him. He proved all the medics wrong, and he still continues to do so. Granted we still need more movement, and boy do I need to hear his voice. I know that day will come. 
I have no care package, (which was my choice) and community physio has been non existent , only what I do with him. We need to get Nick's muscles strong again in order to have any hope in standing and walking again. 
After research and physio advice, we need to get an electric standing frame, which will build up muscle and strengthen his body. I cant get one funded , so I am going to try and get one myself with some help off family and friends. Now these frames are not cheap. I have seen one on Ebay for £995 plus postage. But to buy one from a retailer we are looking at £3000.
I dont ask anything from anyone , until now. Nick needs one of these frames, I need that bit of hope that he will walk again.  
So please Nick's friends, my friends,  let's see what we can do
Thank you in advance, from me and nick xx
