Hiring someone to help recover my NavCoin Wallet.dat Payment in BITCOIN!

As the title states, It's got to a point where I've literally been pulling my hair out for a week now stress levels have gone through the roof,Im looking for someone who is experienced in recovering Wallet.dat files, as mines become corrupt and I'm in desperate need of the Private Key! I'm offering to pay anything up to $250 in bitcoin if recovered! I'm not super experienced in linux or python or c++ or any coding language for that matter but I know certain things! I'm looking specifically to have my NAVCoin wallet recovered I'm unsure of what bytes I need to be looking for whether it'd need to be specific for NAVCoin or whether its the same as Bitcoins, and if not I need a way of being able to identify those bytes so the Private key can be searched for manually, I've tried PyWallet to no Success! All help is seriously appreciated and if recovered like stated already I will be rewarding the person who help achieve this up to $250 in BTC!
