Transform non-responsive wordpress theme to responsive - repost

I run a Wordpress non-responsive theme. The look, style is good. However I want it to be 100% responsive and in full agreement with the Zurb Foundation framework. On small screen devices the left sidebar should go to the bottom. Before the footer. The look must remian the same. Of course if necessay minimal differences can be. For example on mobile devices it is better to have a differen nav menu touch ready. The footer should also be responsive as the whole site. An example of wordpress responsive site is here and this is the behavior I am looking for: [login to view URL] The content column now supports for photos large 913px. I need this column (for homepage, single, categories, tags, etc) to be enlarged to support 1000px on big screens. The site is [login to view URL] I will evaluate the bids. For me time is not important. I can wait. The most important for me is a good price and good work. It can take from 1 day to 2 months. Only fixed price. No hourly budget.
