Looking for individuals for affiliate marketing for a stock training company.

One of my clients runs a stock market trading training company. We need someone who have expertise on Affiliate marketing and can generate leads for the website. This will be a long running engagement. We will first engage the person for 1 month and if he/she is able to generate successful leads , we will make them permanent for long term (2-3+ years). Also we would need someone who would be comfortable with conference calls (skype/whatsapp) etc on a regular basis. This engagement is specifically about Affiliate Marketing only.
