In this instance, I am referring to two people, so the your is plural. My question is if I should use "support" or "supports". Support can be talking about the collective aid of many people, and supports can be talking about multiple people's individual aids. To me, I can't really see a difference. Here, "everyone" is referring a group of people that includes the two people who might pledge their support, the speaker, and about fifteen other people who don't have anything to give, but who will also benefit from this idea being proposed.
I'm thinking of either using
"If I can get both of your support(s), I would like to propose an idea that will work out in everyone’s favor."
or
"If I can get your support(s), I would like to propose an idea that will work out in everyone’s favor."
It sounds better in my opinion to say the first one with an "s" and the second one without. It's the word both that makes support sound better with an "s" to me. Is this the rule?
See Jennifer Rappaport's analysis. But 'support' here is noncount.
