Social Media Management

I want to hire someone for 1 hour/day for one month (30 hours) and then maybe rehire on a more permanent if it goes well.

I need someone to help me to:
- Manage my various facebook groups with 250,000 members total. Adding and removing/blocking people from the group.
- Monitor posts to make sure they are relevant to members
- Lead Generation for my property business where i buy and sell garages and houses
- Increasing advertising revenue from the facebook groups

Must have relevant social media/marketing experience and be able to start immediately.

Thank you
