I would look for good track record, and verify their references, as with any type of position. If I'm looking for a good developer, I want to see their past projects or companies involved, and possibly some source code. I'll probably ask them to write part of an app on the spot and see how they work. The best hires are the ones who really enjoy what they do, and those people usually have interesting side projects they can show you or talk about. I imagine a sales person who is good at his job will be able to show you exactly how he helped out the last several companies he worked for. He should probably be able to "sell" you on why he's perfect for the job ;) I probably wouldn't hire a sales guy until I have the product fully developed and tested, have happy customers, and know there is a strong demand. I wouldn't rely on your sales guy to push a product that isn't ready.
