Promoting coupon codes

I have an online shop selling handmade ceramic items, shipping worldwide. I am looking for someone to promote my discount coupon codes. This is a long term opportunity. I am not interested in post-and-run promoters. I will select only very few, no more than 3, and I will create a custom coupon code for each of them. The ideal applicant has an established online presence (Twitter, social media, blog, etc.) with many followers, ideally with a home improvement, new home, gift ideas subject. He will be free to post any item from my shop, to make a review or to create any content which is engaging. He is free to post as often as he finds it suitable. Obviously, somewhere in his post(s) he should include the custom coupon code given to him. Using that coupon code I can track the customers driven to my shop and placing orders. You will be paid a commission once a week. The rate of commission is 10% of the item value. My average item value is $50, so you can expect to earn $5 with every lead which comes from you and evolved into a sale. I will send you a sheet every week, summarizing the sales with your coupon code during that period, and you need to create a custom project covering its value, which will be paid right away. Any request to pay off this site will be refused and reported to the admins.
