Someone asked me to post a picture to promote their product that's related to my niche and asked how much I would charge. I have 88k followers and get 6-8k likes per picture. How much should I charge them? And if I do it through PayPal, would asking them to send it as a gift ensure that I do not get charged back? Thank you!! EDIT: I am in the cat niche, so please let me know what prices would be appropriate for that!
