I would say to charge based on how complex they are, so if somebody wants something simple it isnt that much, but if they want something more advanced then it can worth more as you are spending more time for whatever they are asking for.
Thats a lot you know, if its adjusted for how much roblox takes, thats about $40 USD (convert that to whatever currency)
Honestly, base it off of your own preference. To me, 6,000 ROBUX seems like a very good price since I’m broke. However, you need to take into account:
1. How many days did it take to write the scripts? 2. Are you an experienced scripter/making advanced scripts? 3. Research the person whos paying you. Have they ripped off people before?
