would you sell your feet to me like this?

i once talked to a seller who sold pictures for $3, i offered a payment plan to them where i would pay then $25 a week ($100 monthly) to get sent content randomly throughout the week like 1-3 pictures a week and they counter offered with $1,500 monthly… never in my life have i come across a seller who counter offered with prices higher than some of the top sellers in the community. was i in the wrong for offering a payment plan, or was i being ripped off? let me know, and if you enjoy the idea of this payment plan, please dm and letting me know!
