Brody's fast track Visa

I moved to Scotland on 26 December 2019. My 8 year old son, Brody stayed in South Africa to give me time to get settled and make sure things were stable before bringing him over. The time that we were supposed to be apart was between 3 and 6 months. We are coming up on 6 months and Brody has really been struggling emotionally with our separation. He cries inconsolably and tells me he cannot deal with being away from me for even one more day. COVID-19 has resulted in us not being able to finish his Visa application (biometrics being completed). The type of Visa he needs can take months to process. We don't know when the process will be able to begin again but when this does happen there is a super priority service that can be paid for to ensure the Visa is processed the day after biometrics are done. This is something I really want to be able to get so that we can be reunited as quickly as possible  This service costs £800 (about R16 000). I realise this is a tough time for everyone and finances are tight. I am asking friends and family that are able, please help us out in this difficult time as I am unable to afford this extra cost on top of the Visa fee. Any amount will be so greatly appreciated. No amount is too small.
