Nonsense. Futures and options and how to use them to hedge exchange rate risks are covered in any good masters in finance (source: I have a masters in finance). You don't even need any advanced math (the ancient Greeks were using options to hedge their olive harvests).
The bank teller might not know about them, but the bank most assuredly has people that can help you.
Also, contrary to what your posts suggests (any serious amount of money), the amount of money has no bearing on how you would hedge its risk.
