Looking for a professional Social Media Manager to run social media sites

Heartland Computers (heartlandpc.com) is looking for a professional social media manager to design, create, edit, and post to our social media pages content. Currently we are very active on Facebook and have grown our followers however we don't have the time to truly provide our followers with the content we would like. Plus we would like to grow our brand using social media. Again we have a active facebook page: https://www.facebook.com/heartlandcomputers
This position would also take over creating and developing our Twitter, Linkedin, and other social media pages.
Job requirements:
2-3 posts a day with images
Fresh relevant Image design with each post
Images may be used from our website
Additional store/product images may be requested
Holiday and other nationally recognized days must have relevant posts
Use of provided videos and images
Other content as needed

The person or company we hire must be great at creating a schedule and emailing the scheduled posts BEFORE posting to our accounts. Failure to do so will lead to termination. This person must be creative and know a little bit about computers and the computer industry. We are very easy to work with and love people who are motivated and get involved in growing our business.

Work above and beyond our expectation will lead to bonuses as we reward hard work.

Please submit example work and ask any questions before hand, thanks!
