Gmail hacked

My business Gmail account was hacked within the past 24 hours and I was unable to recover it through the Google account recovery process. Sensitive business emails could have been exposed, so I'm looking for an expert to help me secure the account. The right individual should have a good understanding of cyber security and be able to offer a prompt solution. My goal is to regain control of the account and ensure that nothing else is compromised. If you have the necessary skillset and are interested in helping me solve this problem, please bid on my project.
