I have an account with just over 100k followers getting 6k-10k likes on my pictures. I've only really sold 2 shootouts and they were both for a company promoting a project so I charged them $150 US ($180 for me) for each one. Someone just asked me to feature their cat (my niche) and was willing to pay. Usually when people ask I just do it for free if I like the picture, so I was obviously not going to charge them $150 for that. Instead I asked for $15 and they agreed but now I feel like that was not the best decision to make. If the shoutout I'm selling is just a picture in the niche and not promoting a business or product, how much do you think is reasonable for me to charge?
