Makeover of existing small (5 page) site and make mobile compatible

Small web site update/cosmetic makover I have an existing small (only 5 pages!) web site that is in need of a cosmetic make over and update. I am revising slightly the types of services promoted that should simplify the site further. I can provide updated text for the services on offer, but I am open to suggestions on the layout/style etc. View the current site at [login to view URL] Although this is a B2B web site I would be happy to look at design suggestions to enhance. I also require the site to be created as a Responsive Design so it works also on mobile and tablet devices. Main requirements are; 1) Update the look and feel of the site to make it more modern and user friendly. 2) Look and feel needs to be oriented to a business target market (Australia). 3) Re-design must be a Responsive Design for mobile device compatibility using regular HTML / HTML5 (not CMS / Wordpress / Joomla). 4) Hosting is Linux/Apache based, one PHP script is used for processing an enquiry form, this should be retained. 5) Re-design must be SEO friendly. 6) Would need to retain current company logo. 7) I would need to be supplied all files so I can take over maintenance. 8) All copyright and intellectual property rights to transfer from the developer to us upon completion. 9) Any pictures used must be licence/royalty paid (exiting site pictures are licensed). Please respond with samples of work on other B2B oriented sites. This would be a small and easy task for an experienced designer/developer.
