Need a reliable marketing agent to help promote online courses (commission-based)

Hi, I need a good internet marketer to help promote my Udemy courses, mainly on the areas of learning mathematics and physics. I will provide with the course coupon codes and the weblinks for the courses. The agent will use the weblinks and do the internet promotion at his or her own expenses. Below are more information: 1. Commission: 50% of the final selling price that I receive from the sale. 2. Requirement: proven track record of successful internet selling, preferably in the area of online course selling. 3. The person has to be honest, reliable and fast response to questions. He or she can use any form of internet marketing tools i.e social media marketing, affiliate marketing, email marketing, SEO etc... 4. There is no requirements for the ethnicity or race of the person. As long as you can do job, I will let you promote my courses. Further discussion about collaboration can be discussed, such as the tracking of the coupon sales etc. 5. Refunds. Udemy practice a 30-days money-back guarantee refund policy. Hence, for each sale made through the agent, the commission will only be paid after 30 days if there is no refund request from the student. 6. Links to my two courses: [login to view URL] [login to view URL] This is not a scam. I am genuinely looking for a reliable person or organization to help me with my course promotions. Look forward to hear from any interested person who would like to work long term with me. Thank you! regards Daniel (from Singapore)
