Required software development freelancer for Network Admin / Computer Expert job

I need someone with Network Admin experience for Microsoft Server 2012 with knowledge of creating / updating an active directory with username, password setup, monthly maintenance of both server as 4 workstations including my laptop which is also connected...occasionally its connected with ZyXel Router) in a small offices setting. Also, will need to do some minor computer maintenance and pretty much act as my network admin. I need someone whom can be available during US Central Time hours for various remote sessions to keep the office running smoothly. Will need to be able to perform and work via Teamviewer. I am looking to clone current C drive on my server to a larger drive for better overall drive performance.

We currently have Security essentials on each computer, but I will be upgrading to something more secure so suggestions are welcomed.

I will provide a current network diagram of office / network setup so this should be a simple task. I need this done asap!

Thanks
