Visas to save my siblings future

Its always been hard asking for money as its something we dont do in our culture but my family are struggling to come up with £17,000 to pay for their visas for permanent citizenship in Kings Lynn, Norfolk England and I thought this is the best way I could help from a far. The fees for citizenship have spiked up by 18% since 2017 from £1800 to now £2,200 per person which my parents were only made known of, as of recent. My parents are both New Zealand born that decided to move their family to England for better career and academic opportunities.  There are 6 children including myself under the age of 24. My siblings were raised in England most their life. The oldest, being myself and the two youngest were born in the U.K whilst my other siblings were born in New Zealand.  My parents moved to England in the 90s where I was born in 1994, later returning to NZ and eventually moving permanently in 2004(to Ireland) and then 2008(to England) which was 10 years ago. As a family we were forced to move back to NZ 2011 for this similar situation. My parents are very hard workersp and they are dedicated to their family and community of Norfolk. My Dad has been driving 3 hours everyday for his job, which he would usually leave on a weekly basis to camp in London and travel back for the weekend to help my mother out. However now my dad has been left without a job and has been stood down and only given a month from his job to try find the funds to pay for his visa. My sister and two other brothers were given scholarships to go to private schools because of their high academia, sporting and creative arts attributes but may not be able to proceed due to them having to leave the country. Both my parents will do anything for my family and whilst my mum is a kitchen hand at the local school my father is a overhead powerlinesman who works abroad they will always make sure my siblings tuition fees are paid and they have food and a roof over their heads. Both my parents are coaches for the West Norfolk rugby club and volunteer their time anyway that they can. My parents and siblings deserve to stay in England.  Please help our whanau(family) have a fair crack. Much aroha (love) and Appreciation for all donations. Thank you
