auto responder series

We are looking for an experienced writer that has done auto responder writing before. Pls do not apply if you have never done them before. Each retail customer will have a series of 10 ten auto responder letters written. The letters would be sent to current customers and potential customers that fill out a lead capture form. The letters would be approx 250-500 words. The project will start in january, but we are beta testing now, so we could have work in the next two weeks
