Van stolen with months worth of stock

Hello, I'm fundraising on behalf of my Dad who is completely computer illiterate, but very grateful to find out a space like this exists!

On Monday my Dad's van was stolen close to Barking market, it was full to the brim with stock, his market set-up, the keys to his unit and everything he needs in order to make a living, not to mention personal items that are irreplaceable. The stock was to sell on Barking Market/Deptford Market over the next few months - without this stock or the money to re-buy this stock he is unable to make any income.

My Dad is almost 60 and is the provider for his household and last week fell off his van (before it was stolen) and cracked his shoulder (luck sadly hasn't been on his side) my Mum is unable to work due to having Myalgic encephalomyelitis. Without making this sound too much like a sob story, they are now in a very difficult situation and I very much wish I could put £10k+ in his account myself, so this is my best attempt at trying to help them out of this horrible situation.

He has reported the van as missing to the police, and he has been in contact with his insurance, sadly they will only cover some of the cost of the missing van and absolutely none of the contents of it.

My Dad and I would really appreciate any help at all, thank you so much for taking the time to read this.
