Okay, well personally I wouldn’t charge for that because I don’t think that’s enough content to be charged for (I considered 3 scenes), but it’s your decision to consider in future.
I know there are a lot of people who code for others for free, but I honestly support the idea of charging those who want your expertise and help with coding most of their episodes or their full episodes, especially if they need your help regularly or want you exclusively to continually work with them. It requires a lot of time and effort and time is money.
