This offer looks rather professional, Op set clear goals and explain his target, but I was under the impression that this job is worth a little more than $5 per hour.
My friend is a web admin, he does similar stuff (if not exactly the same...) and he is earning $1000+ monthly, why there is so much difference in salary?
exactly. One would have to pay $300/month by hiring just a social media marketer and that is just the basic social media such as facebook, twitter, instagram and pinterest. SEO's get paid for more than $1000/month.
I can see some webmaster that have managed sites for someone else, they are paid for a minimum of $3/hour. If you can increase the fee, the more applications you'll probably get.
