You should have a very high expectation of sales results from them, and you should give them a guaranteed commmitment that you will measure their results, and you should follow through on that commitment. Salespeople are notorious for giving excuses when they don't meet the sales targets they agreed to.
Fire them if they haven't got results within a reasonable timeframe which you both agreed to.
Offer nothing you can't back out of (like equity) until they have been on board 12 months at least and proven themseves invaluable.
There are lots of salespeople out there who can sell themselves to prospective employers better than they can sell your product.
You must learn how to be a good manager of salespeople rather than trying to "find a good salesperson" who will magically start bringing in the sales for you.
Probably you should do it yourself - you need to know first hand how hard it is to sell your own product, and you know how to succeed selling your product. Only with that knowledge can you effectively manage someone else to do the same job.
