Hello,
Having studied your requirement and html link we a company with skilled developers for HTML, CSS, Wordpress and other CMS, feel very confident in taking up your job.
The 6 main tabs with more links in the footer section, this site seems to be easily do-able in wordpress. Since the layout and color scheme are also simple and interesting, there wont be much changes required in this respect.
Other optimization might be required at the time of development. Hope to hear from you, a positive reply, soon.
