School trip to USA for amazing daughter who can't afford to go.

Hannah is an amazing 16 year old girl who has struggled with dyslexia her whole life, despite this she works really hard and has done well at school has passed her exams and is now in year 12 at Christchurch Girls High School. We were accepted to this school out of zone and they have been fantastic helping her achieve her goals. She is wanting to go on the civil rights tour next year with her fellow students but I am really struggling to pay the money required $7800. A lot of students come from wealthy families and are able to afford the payment. I work very hard and have been supporting my husband who has had severe depression requiring hospitalization on more than one occasion. He is better now and is making a recovery back to work slowly how ever on very reduced income. Hannah is a really good girl and works part time at Pak n Save and is trying to help us raise the money. Everyone wants the best for their children and I lie awake at night worrying about how I can possibly pay for this the simple fact is I can't do it on my own. If anyone can help us even in the smallest or ways I would be eternally grateful :)
