Required software development freelancer for Cyber Forensics job

I am suspicious that one of my email accounts is currently being attacked or subject to surveillance. I have received two phishing emails in the past two weeks from two separate trusted senders that targeted my email username and password. I put in the wrong information in response to the first phishing attempt, which prompted the second phishing attempt from another sender immediately after. The timing was very odd to be coincidence such as those two accounts being compromised and the hacker targeting all contacts. I believe that my account was the only account being targeted.

To further cause concern, I received an email yesterday from another semi-trusted party who I believe was communicating on the other end; however, the message came with a warning that the digital certificate signature for the sender was invalid or untrusted. I am not an expert but I did use program called CERTivity to analyze the credentials from the invalid certificate. I created some screenshots that I can share with you in a PDF file if you are able to send me a proposal. I am not sure how to interpret the details. A few suspicious items were that the certificate appears to not be revoked currently; however, when I viewed the associated certificates list, I found 51 revoked certificates that seem to be associated. I will share the original invalid digital certificate through chat if you can share.

I would love to pay you a reasonable fee to help me analyze this problem to identify the type of attack and any information about the attacker that you might be able to help me find. What would you charge for this?
