How many sales people do you already have?

Do you sell? or your co-founder(s)?

The answers should be: (a) more than 5; (b) Yes; if No, then should be (c) Yes.

I am not being snarky. It has been shown time and time again, that when you are starting out, at least one of the founders should be selling. Hiring an experienced sales managers will not result in sales, they are "managers" so they will hire more sales people and thus increase your burn rate.

Ok, I guess you don't believe me. So why don't you let Google be your friend and find a few articles along the lines of "Things I wish I knew as a startup founder".
