Seriously, hire someone who likes sales.
I hate selling. I like building. I started my company in 2006. In three years, I signed 3 deals. Then I found a partner who lives and breathes sales. In the past three months, I have signed two additional deals and have five more in end stages of negotiation. Thanks to our new head of sales, went from actively talking with 15 concurrent prospects to actively talking with 150 concurrent prospects.
Don't kill yourself doing sales. Kill yourself finding someone who will do it well and love it.
Edit: I should mention that the average value of our contracts is going up too. Well-executed sales strategy can generate more revenue off of the same quantity of goods sold. Don't underestimate it.
