The way I hire anyone is to find someone who's currently employed in that role for a company in my existing market. You can find that person using a few techniques.

1) LInkedIn: Search who's currently doing technical sales for companies similar to yours, and reach out to them to get advice on "How to hire someone like them?".
2) Customers: Connect with a company using a similar product and ask them who's the most impressive technical salesperson they've met - contact that person.

Another technique for finding-the-right-person is to search on LinkedIn for a person who previously worked at a similar company that would manage that kind of person (ex: Sales Manager) and ask for advice on hiring... then you can ask who they worked at, at the previous company that impressed them.

Build the list using this technique, then win them over to join you for US domination :).
