Yep I agree, it’s a bit off-topic though. Still for $3500, you’d need maybe 20-30 people willing to put in $100-200 each. And you may be able to make back most or all of it by selling it later, but there’s no guarantees there.

So if you’re passionate about the film then go for it! Start with what you can put in, and then look for other people who would be willing to contribute. Once you own the film you can then store it and begin collecting money for scanning costs, etc. It’s not as if it has to be scanned immediately!
