wordpress wprealty king power plugin customize

We currently have a website using a theme called King Power from a company called Good Layers. We also have a plugin called WPRealty. WPREALTY allows you to take all of the information from a Real Estate database and import it into your Wordpress Database, including images. Our problem is, the listing page which shows the images in a gallery and also shows all of the listing infromation, is an external page, it currently calls its own css. We need to integrate it into our Word Press template CSS, we need to make the entire page responsive, we need to integrate it with our Word Press template CSS by calling different divisions within our wordpress css. We need to also recreate the gallery, the gallery currently is very simplistic. We also need the gallery to be repsonsive. Laslty, we need this within 2 days.
