I am a nutritionist by profession, i opened a website which im gonna use to help people lose fat. I will charge them 50$ a month, for every 50$ they pay me, 10$ is yours. You can advertise whatever way you want. In first email with a customer i will ask about their weight(and other related stuff) but also how they found me. Make sure to let them know that you brought them and you will get 10$ out of every 50$ they pay me. Pm me if you are interested. Cheers.
