Freddys hypo awareness dog

As most of you know Freddy has been diagnosed with Type 1 diabetes. He has no hypo awareness at all so we would like to get a hypo alert dog. This could potentially save his life. However there is a 4 year waiting list!!! I can purchase one at the sum of £5500. Therefore I need some fund raising. Has anyone got any ideas??? Is there anybody that can help with a charity event??? Please please help
