Exisiting site needs to have one link updated to lead to one new page - header, footer and ALL of the design is complete - just need an external link to apear within the current "template" and change NONE of the design or layout of the site. External link is to a real estate like site that is paid for and legitimate for the site.
Again just have the external link load into the content area of the existing site on one new page and change one link on and existing page to lead to it.
All site files and code can be dowloaded if you need it - I only need the 2 PHP pages returned to me. Need this work completed VERY quickly so do not bid if you can not do this immediately - should be VERY short work for a PHP professional.
