Revise a landing page website made with wix

My website is a landing page of a startup idea I had. It is a website related to rentals. The website totally have 7 sections that I built with Wix but need some refinement. The six sections are: header, mission, product and services, delivery method and retrieval method, introduction to the founder, contact info and sign up form. I wanted to combine the last two sections but was not able to.
