You may not think they are hard to set up, but some of your options are indeed complex, and have LOTS of caveats, provisos, limitations, GOTCHAS, etc!!! I can't count the number of clients and forum posters who have messed up their HA/DR (WAY more than have gotten it right, I promise). PLEASE see if there is money in the budget to get a qualified consultant on board to help you a) figure out what you REALLY need and b) help you pick the right option(s) and c) help you plan, implement, test and set up maintenance/monitoring for it!! Remember, if you mess this up the BEST that can happen is that you are offline for an extended period, very likely with some data loss. The worst is a complete and total loss of all data - unrecoverably so.

Some thoughts: how long can you be off line if you lose your primary DC? How much data can you afford to lose? Do you want completely automatic failover? Can you afford your choices or do you have control over them? What is the bandwidth and latency of the network pipe between DCs? What is your backup and retention policy? Will you need to access the secondary for any purposes? The list goes on and on...
