I need follow up sales calls to new businesses

Dear Sir: I understand the high need of qualified staff for the duties mentioned above. In this sense, I must underwrite that although I am new as a freelancer, I have a high level of english language knowledge and client assistance that includes email and conversational skills (face to face and over the phone). In relation to the language, my experience covers the work with foreign colleagues in an american cruise line company, having therefore developed sound english writing, reading and oral communication skills. On the other hand, I possess experience regarding the field of customer attention in a hospital, and previously, in an insurance brokerage entreprise where I trained and performed sales of robbery, liability and traffic-related sinister policies for new and used cars. To meet this end, an uncountable number of mails, daily phone calls and visits had to be made. Furthermore, my proposal is to perform the tasks in one calendar day. However, in case there is need of additional work, I can broaden this period to as many days as you may specify. Finally, I must add that I am willing to put my best effort to develop this project as expected. I really hope I can count on you and if this ends up being the case, I will deliver you my email and phone number for further contact and details. Best regards, César Jiménez.
