How to do this?

What are you trying to achieve:
Hey everyone, I need to add an edit button to my repeater to edit the content inside. I also need to add the owners username and a clickable button to view their profile and message them. Think of this as the facebook marketplace for musicians. Attached is a picture of the site.
