Registration Page

Ok, I feel like a complete idiot but cannot seem to find how to get the Registration Page for a membership package on the site? I have all the fields set up that I want them to input. I want them to pay for membership package first then create their listings. I have a “why you should join” page and at the bottom I would like to put a button for them to “Become Member Now” and take them to registration page. How do I only show listing options after they have signed up? Thanks so much!
