Adding Facebook & Twitter icon to my website

Hi, I need my Facebook & Twitter page linked to my website. This means adding both Facebook & Twitter icons at the bottom of my website,so when you click on the icons you will be re-directed to my Facebook & Twitter page. (the same as it works on this website, freelancer.co.uk) This is a simple project,& should take minimal time to complete for people who know what there doing. I need this completing as soon as possible,so please only bid if you can start this right away. Thanks.
