Correct Issues with Website. - open to bidding

Recently our website hosted at Nexus was hacked. It is a Magento cart with a theme placed on top of it. I think there is a twitter feed plugin as well. SSL is TLS 1.2 128-Bit but doesn't appear to be over the whole site - just that specific to clients/purchases. Website is not in CloudFare. I need a Freelancer that is excellent at website security and if chosen this project might be re-made/upgraded to an NDA. First the Freelancer will discover all of the security holes. I want to know what specific hole (Injection [CSS/Java/XXS/SSI]), I want to know what specifically you typed where. I'll be running though the same steps to reproduce the issue for our managers responsible for the site. I want you to recommend and run analysis with websites to check for all holes. I want to see these reports and again, show to management. Once we have discovered all of the issues, I want the Freelancer to fix them. I want the freelancer to show me how he did it and answer questions (so I can do it myself) on other sites. Your bid should: 1) Be accurate for price and ETA 2) Tell me how you will complete this project 3) Let me know your availability / time zone 5) Say "Security" as the first word in your Bid I am happy to PM the link to a select few I feel fit for this project. For now, assume besides an SSL that nothing was really done for security. THIS IS TO BE COMPLETED 3/21-23 AND REPORTED ON THE 24TH (IN DETAIL) Good luck. I'll contact you via PM if interested. Thanks for your time.
