edit existing php questionnaire to avoid copyright - make all small changes

PLEASE READ need a php expert! PHP files or PHP websites I have a website that has already been created it's small it's like a questionnaire maybe 7 pages/questions and I need get to avoid copyright infringement since it's an exact duplicate from another site so I will leave the pictures icons the colors and a few of the questions to change so that I can avoid copyright infringementI also need the copy of the site to be added to a different domain name once completed I would send you a detailed explanation on all of the pages and how I need them to be changed The site is very much like a questionnaire so there's very little content but I will need the images to be swapped out and the content to change and I would want to change the colors to make the site unique enough to avoid copyright - I need it completed within 48 hours and my budget is under 80$ must work quickly and be creative to make obvious changes on your own. all images need to be replaced colors. font....
