But a third party could buy into it. If the company has real potential then I would look for a strong business/sales person who might be interested in buying your partner out. It shouldn't cost too much if you aren't making that much money, and this way you know the new partner is serious since he is putting money into it. I would talk to your partner and say "let's come up with a timeline where you hit these goals or we look for a third-party person to buy you out". If he can hit those goals, or hit those goals with the help of a commission only salesperson then your problem is solved. If not you start looking for a third-party.
