I'm sorry to disappoint you, but things are not going as you imagined.
first, is it really your wallet, and how we can be sure that it is a hack and not actually a legal agreed transaction? you are looking for a white hacker to commit a crime and take someone else's money. then that someone will hire a hacker again to bring back the coins and so it goes round and round. you thought that's how the crypto network works?
Do you think it's all easy, and hackers do it for a salary? if they can do it already, why do they need you to give them a job, he'll do it without you and keep all the coins to himself.

btw. your wallet is compromised, but not because of a wallet hack. Your device where you host wallet or do access to them is compromised and hackers took necessary info of your wallet & funds, through that hole.
