If at all possible do your own sales as the owner of the business. Sales people are very expensive, and once they reach their comfort zone they cease to be productive. Even a busy business owner can make 30 cold calls a day.. that works out to over seven THOUSAND calls a year. Do that year in and year out and you will have more business than you can possibly handle. It's the first thing I do every day.. I make my 30 calls. At best I've got a lead or two to follow up by midmorning. and at worst I've been humbled by 30 people who have no use for my services but have reminded me to appreciate my current accounts.
