I think you are overthinking things, making yourself more concerned than need be. Big companies are checking boxes during the RFP process and want to make sure you have thought through problems. No one can tell you everything you need in your DR/BCP (disaster recovery/business continuity plan) without understanding your solution and problem space.

https://www.smartsheet.com/disaster-recovery-templates . -- Has lots of different templates to start from or get ideas from.

DR plans could be as simple as a couple of pages or as complex as a few hundred (though I find those useless personally). Answer the key questions, if you are using the cloud to host you are in luck because it simplifies things drastically. If you are self-hosting on your own co-located servers, then you are in for a bit more work. AWS and other clouds have products to assist you and also have templates to help you answer key questions usually. again you have to use what you need from it and customize it for your company though.

I am not trying to be a dick or anything and I hope it doesn't come across this way, but the DR plan for a small SaaS company with one or two employees will be drastically different then one with 100, 1000 or more employees. So having no clue what you do, what your product does, or what size deal this is it is hard to help point you to a specific template that might be more helpful.

Just a note on the RFP process (if you don't already know).

RFP's can be awesome, or they can suck the life out of your company. If you are answering an RFP for a < 5 figure/month deal it is almost always a losing proposition. Most true enterprises will spend 100-250k without needing an RFP. Government, or government agencies are different of course. But RFP's can take you a few weeks to put together properly so you have to weigh the opportunity against the cost to respond. Not saying don't do it just recognize and evaluate the costs. I responded to some RFPs where they required you to be on-site for the question/answer session or you would be disqualified, so now add in air travel and hotel rooms, plus the RFP costs. Some of our RFP's were really awesome and we spent a week putting an answer together and got a decent deal out of it, others we took a month and spent $15-20k only to be told we didn't qualify (when in reality the company already had their chosen vendor and just had to check the RFP bid box), so just guard your time and money when doing RFPs, and try to get a feel for the situation. And remember, probably a good 50% of the RFP process for enterprises is box checking, and once you get past that stage they'll be more open to working with you.
