Fundraising for local youth football team

My son has just joined a youth team all pretty much new players so still learning how each other play etc. They don't currently have a sponsor so looking for fund raising ideas. I was going to do a amazon gift voucher on here (£25 at £2 a go limit of 25 people or something, would need to do around 4 of these to make it worthwhile)as you can send via email but not sure if it's allowed. Any ideas are more than welcome. I am currently doing a raffle on Facebook but there are only so many raffles people will do.

Thankyou
