clone website - change design so not identical in look

want to copy function/design of this website. no actual transactions occur on the site b/c it's a website that just redirects to affiliate links. i believe this site is made with wordpress, but not certain. want it to look very similar in framework, but just change up the "theme" like colors and some images. i'll change up some text so it's not all identical. pretty much it. i have several customers that want this site built, so there will be more than one. please quote me on original site and then message me cost of creating dupes of site for different domains. thx!!
