I need help with member login for my WIX website.

I'm looking for someone with familiarity with WIX. A lot of the work is already done but I need member login where when someone signs up for on the website they will be redirected to a page to update their profile info. Once updated they will be redirected to a dynamic "order" page. This dynamic page needs to be "dedicated" and have it's own url. When someone logs in they need to be redirected directly to the orders page. I also need a button to be created that when clicked, they are asked whether they are sure and if they select yes, an email gets sent to me and it creates a "red X" above it.
