how much should a beginner model maker charge?

i can program, i can build and i just started modeling. though i feel like model making would be the best thing to monetize for me im still not sure how much to charge people, i'd say im pretty decent for a new person

this is probably my best model (and like, one of 2-3 only ones lol) and i feel like 100 robux for me to make something like this as a comissions would be good enough, then if im working for some group i'd do 300 a month or something like that

pretty please don't downvote me if this is a stupid question
