Responsive Wordpress site from current HTML site

My current HTML site is here - www.esafety-adviser.com

1. The goal is to convert the HTML site to a responsive WP theme that looks as much like the current HTML site as possible. Ideally if you can find a template that can be manipulated that would be good. My current blog uses the Karma theme. As you will see, the HTML site is clear, concise and simple, no fancy graphics or flash, which is exactly what I would like.
2. My site already has a WP backend for the blog, so there will be no need for hosting/SQL setups. The current blogs posts will also use the same theme as the rest of the site.
3. I like the current site very much, and so do my customers (mainly schools), however I now need to be able to use it not only as a professional front-end, but as a CMS as I have many resources to upload.
4. I am a competent WP user, so the requirement is only for the design and for the current information to be copy/pasted across. I can do the rest.
5. In the near future I will be adding e-commerce so this will need to be a consideration. I will also be adding an options page (such as this - http://themes.truethemes.net/Karma/features/pricing-table-demo) so that will also need to be a consideration.
6. Page names will need to reflect exactly the current page names.
7. As the current site is live you will need to host whilst the work is being carried out, alternatively I can grant a login to the current WP setup so that you can use that.
8. When bidding or replying, please include links to previous work.
