Customize WC Marketplace Front-end Manager plugin

Hi, I am making a marketplace using Woocommerce + WC Marketplace bundle plugins This marketplace will not use payments trough the website, only contact seller inquiry. Members have to buy membership and can then acces the WCMP Front-end manager dashboard, to add products / chat with buyers/ buy top ads / manage store [login to view URL] please look at this file of how I would like my dashboard too look like( Just like the dashboard of [login to view URL], very user friendly! Now it is too hard and you can't see the header / footer of my theme anymore. So I am looking someone experience with changing look and feel of WC Marketplace front-end dashboard, and add a function where users can buy top ads (I am using Ads pro plugin for making my ad zones)
