Blog Posting and Social Media marketing

I am a graphic designer, I sell computer Graphics and Photoshop tools. [login to view URL] I need someone who can help me post my work in the most famous social networks to get extra visibility. In particular: Pinterest, Flickr, DeviantArt, Dribbble, Twitter and possibly others. The candidate should take care of my profiles, posting my work with images and link to the shop. I will provide all basic the assets and I will also show you how to do the job. It is also required that you use my profiles, be active and post comments and likes occasionally. English is a required language, but you won't need anything more than intermediate level. It is required that you know how to use an image editing tool, like Photoshop or Gimp, so you can cut the images according to the Social Networks standards.
