Build a simple (responsive) website and integrate a Paypal checkout system

I am setting up an online recruitment company. I have already designed the website myself. Here is my design: [login to view URL] As you can see its a relatively simple website. The problem with my design is that its not responsive. The size of the pages do not adapt to the screen size / resolution of the user. I need you to redesign the site. The pages must adapt to the screen resolution of the user so that everything appears correctly regardless of screen size. I will also need you to integrate the Paypal checkout. I will probably opt for Website Payment Pro (hosted solution). I am not entirely sure which Paypal option I will select because the Paypal account is still being set up. The process should be complete by the end of this week at the latest. I would like you to stick closely to the design that I have provided, but I also want you to add a professional sheen. Feel free to change things like the font, spacing colors and general layout in order to make the site look more professional and sophisticated. I will send the images that I used through the freelancer messaging service. You can then add these to your redesigned version of the site. I will also need you to show me how to update and administer the site so that new content can be added on a regular basis. I would like the website to have a back end that is simple and straightforward to use.
