Convert WP multi sites

We have eight small multi sites (7 are only couple of pages; 1 has several pages) mounted on a main site presently on the wordpress platform. We have already converted from WP and hosted the main site and now need to convert the remaining multi sites to normal html/php & css pages to be hosted on our Linux (cPanel) server in sub folders on the root directory of our main site. Most existing menu links, .js & .css on these WP multi site pages can be linked directly to the main site files instead of locally as most scripts and files in the multi sites are merely duplicates of that which already exists in the main site anyway, just with regional specific graphics and content added. All the multi sites will also link any database or shopping gateway urls to the new main sites database or gateway instead of individually. The time period for completion of this is eight days or less. You will need to be highly skilled with WP, HTML5, PHP, CSS, Java Script and server side operation and cPanel. Dependant upon your service, speed and professionalism, this will be the start of much future work over the following years and an opportunity to join our global team. Only apply if you feel completely confident of this task and the time limitation. We have set an expected price of $500, though this is negotiable within reason Once chosen, we shall disclose the urls so you can fully evaluate the job.
