Accidentally sent Bitcoin Cash to Bitcoin address on my Trezor

In 2017 I mistakenly sent 15 BCH to Bitcoin address on my Trezor.
I got an advise from Terzor support on how to recover the BCH using electroncash
Unfortunately I am not a tech guy and don’t know how to use it.
I am ready to pay $500 to someone from Trezor helping me to recover the coins.
