Hi. We run a start-up online magazine/newsletter which has grown to the point where we need a brilliant freelance ad sales person to join the growing team. We need someone who is experienced in selling digital media inventory. It is part time and would perfectly suit a parent looking for something around family.
Can anyone recommend any good agencies (or know of anyone who might be suited to the role?). Any experience of average rates etc would be welcome too as we are just starting out down this road in terms of sales. 
Thanks!
