Always , when I have been asked to make something for another, I go with them to the fab shop, help with the selecting, get all items needed, and they pay for that, plus whatever I feel is fair for my time. I've also enlisted their help with preparations. I learned that the hard way with a friend. I had a sister who gave me freedom to choose for her, and our arrangement was that whatever I spent for her item, I got the same amount in cash to buy for myself. Back in the lean years , that was a blessing for me!
