Social Media Marketing and Graphics Design

We are a recruitment company of home care services and require someone to build and manage our Facebook page and post job adverts on groups to interest workers in joining us. We require about 10 different designs which we can post from time to time. In addition to this, we require our web page to be built.
We are willing to pay a set amount for this work and then pay for ongoing services for posting on a regular groups within FB for these ads.
