Multiple Site SQL+Windows Server High availability setup

Hello, I am looking for someone to help me setup my high availability system. Design - [SITE-DURBAN] [SITE-FALKENSTEIN] DURSVR01 FALSVR01 DURSVR02 --------- WAN ------- INTERWEB -------- WAN -------- FALSVR02 DURSVR03 | | FALSVR03 DURSVR04 | | DURCLU01 ---| DURSVR04 is the AD server in Durban and I will setup FALSVR01/4 with/as an AD server. I will also setup an IPsec link between the 2 locations. I need help to setup SQL server HA. There is NO SAN. Each server must be able to function by itself. I expect this to be a fairly quick setup but I just can't seem to get it right. There is no raid setup on the servers. All Durban servers are dedicated hardware. FALSVR01 is a dedicated server with the rest as virtual. Durban runs Windows Server 2012R2 Standard Falkenstein runs Windows Server 2012R2 Datacenter.
