Sales Support assistant to help us grow our business

I am looking for someone with excellent English and decent writing skills to help us do sales outreach to prospective clients through email, providing leads to our sales team. Familiarity with Outlook and Excel is helpful but can be taught. I hope to hire someone for a long-term relationship who can increase their related skills and duties as we grow. Please identify yourself as serious by typing Mileage Club Support in the subject line of your response.
