Build 3 simple clone websites in 1 hour

I have a small project of a mobile responsive websites which I need to build 3 copies of. Our customers own the original website and there is no copyright infringement. The sites consist of 4 pages (1 index and 3 content pages) and we need to just change the following on each site: - background of the index page and sub pages - change the 3 subpage link images - the themes for the 3 sites should look different (CSS modification, etc) Source code of the sample site will be provided to the successful bidder. BID ADJUSTMENTS AFTER THE INITIAL BID WILL NOT BE ACCEPTED. The timeline for this project is extremely tight ( 3-4 hours ) but is definitely possible provided that the source code for the basic site is provided.
