Perfectly acceptable. More than one sheet have been created on this basis. If you read the checklist linked in the Sheet Request thread, you see that the last advice is offer a monetary reward. Jeff B. said: i'm interested in a similar question - i was thinking of asking an experienced someone to "pair" with me for an hourly consulting fee to make changes to my custom sheet so that I could quickly come up to speed by being able to ask questions and implement my highest priority changes in real time, while also learning more about the system so i could make my own changes in the future, all while kick someone some $ at the same time that they might need. not exactly the same but close. I'd probably be open to that, at some point between working on my current sheets.
