I need someone to help me with my Tweets and keep my blog updated?

[Kimberly]

Should I hire a company who does this, or an individual? How much should I expect to spend? I have a hosting company already, and a WordPress site already set up, but I don't have time to manage it. I don't need something done everyday right now, but I do need someone who would be ON CALL who could add an article and a picture once a week, and watch my social media sites. What kind of an income would I be looking at for someone to do this?

Ideally, I might want a young person to do this, like a sharp witted student who could come up monitor my blog and come up with some tweets that have to do with my interests that are geared to pop culture. What am I looking at here to pay?
