Am I charging too much?

Okay my lovely feet sellers or buyers whoever comes across this. How much are you guys charging for let's say like 7 photos? I've been on for about a week now and the only messages I've got have been bots but I've had plenty of people view my account. I know it takes a while but I also see some ladies have 3 post on their profiles and they're getting buyers. Advice? Thank you in advance!
