Website Functionality Review Before Launch

I have built and designed my website, and I need a professional to review its functionality before launch. The task includes ensuring all buttons and links lead to the correct places, verifying that plugins are up-to-date and functioning properly, and checking for any potential issues.

Hoping somene will be able to work with me so I can follow along and see where any errors are.
Happy to jump on calls or share screen or whatever works best
