Funds for a Great Britain passport

As you may already know I do Acrobatic Gymnastics and have been doing for around 8 years. I moved to glasgow from Slovakia when i was 7 years old, and after one year living in Glasgow I started doing gymnastics and i have been doing it since . So far, I have achieved alot in the sport, however, my ultimate dream is to be in team GB and compete for Great Britain. Not long ago me and my partner received the opportunity to trial for team GB(we were over the moon)however, we were unable to trial because I have a Slovakian passport and not a Great Britain one; we were working so hard for trials and discovering that we were'nt able to attend was really heart breaking for us, it felt like all the hard work has been thrown away. For me to recieve the passport it costs around £1000. I would like to ask if you could please help me with this cost so i can recieve this passport as soon as possible and have a chance to trial next time. I will appreciate all funds, every penny will help! Thankyou very much.
