B2B telesales, to arrange phone appointments for Outsourced Credit Control Services.

I am looking for an experienced B2B telephone sales person to make calls for me for 1/2 or 1 day per week. This could increase if successful and commission is also a possibility.
PLEASE ONLY APPLY IF YOU ARE A NATIVE ENGLISH SPEAKER!
The objective is to get agreement for the prospect to take a 20 minute call from our internal sales team. We will provide company data but you may need to carry out an additional call to establish who the best contact would be (most likely to be Finance Director level). We sell outsourced credit control services. An understanding of credit control and the general workings of small to medium sized businesses would be beneficial.
