Winning new customers for companies and services

Dear All,
I've been marketing and selling for years. First of all, I have been gaining customers for my former Employers, which significantly increased the company's sales.  I worked in the insurance industry, telecommunications, ventilation and air conditioning.  I worked both at home and in the company's headquarters.  I know sales techniques.  My main characteristics are self–discipline, perseverance and implementation of the sales plan.  For me there are no impossible things, it is enough to want and strive for the goal.  I INVITE YOU TO COOPERATION.
Kind regardsMonika
