Has your website ever asked you for a raise? I imagine the answer to this question is no, unless you live in some sort of dystopian for which the rest of us are unaware. I can assume by you being here, that you are trying to increase your sales. Don't make the mistake that most companies do. The answer to your problem is not to expand your sales team, but to diversify the way that you are selling. The best way to do that is by optimizing your website.
