Design Social Media Pages, Headers, Background graphics

Need social media pages created with background graphics, header banners and other related graphics for our business. Please note - this is not about designing our website. We already have a website. We just want you to create social media pages for us including all graphic work. The social media platforms of interest are: * facebook * Twiter * Google+ * Pinterest * YouTube * Instagram You may suggest additional platforms. Conversely, if you think a certain platform is not suitable for our website, feel free to advise accordingly. Please be clear as to what you are proposing, what will be included in your work. Also show examples of previous work. Thank You.
