Professional SalesPerson Needed to Get 300 Subscriptions

I am looking for the best salesperson who has a very good English, high communication skills, be extremely motivated, and interested in sales, to get for me 300 subscribers. I am selling a service about receiving weekly custom, and real letters (4 letters per month), written by me (Vitor Cortes - see a sample here [login to view URL]) to a physical address, like a subscription of a newspaper or a magazine, but this are for letters. This is a monthly subscription and is expensive, just for people who can buy. I think the group of people which can subscribe my service are: rich widows and widowers, rich old people live alone, rich gay men between 40 and 70 years, people with high culture, rich people who like to read, VIPs, people who like to receive physical mail. I emphasize, I think. Thank you.
