You really need to add whether it's a top down or bottom up sales approach AND some sort of overview of the product/service. These factors would change the advice dramatically. Typically you should be doing the sales when you start out, and apply new hires once the sales system is in place (either w/ a cofounder or salesperson). Otherwise you might be screwing yourself or another person. Depending on the product/service... you might be able to get away with a strong marketing effort and kicking "sales" down the road too.
