Looking for help with Social Media including updating Twitter and Facebook

We manage Twitter and Facebook accounts for a variety of different businesses and are looking for a freelancer to help with posting updates to both networks.

The posts need to be engaging and relevant to account's business activities.

You will need to be familiar with the social media, especially hashtags and @replies, in order to help build the client's likes and followers. Would also be good if you were familiar with basic social media marketing techniques.

Most importantly the posts must contain interesting content. I will try to provide as much information as possible from the client's to help write the posts and tweets but you will need to research good content to use yourself.

This is an ongoing job with a relatively new company so I am looking for someone I can work with long term as the business grows.

Please can you bid 'Per Hour' and to help with budgeting, give me an indication of how many tweets and facebook posting you can do in that hour. For instance 10 Tweets and 2 Facebook posts (n.b. facebook posts need to be longer than tweets).

Any questions then let me know.
