Hi C1, IME, as-presented , the inputs and rolls are not difficult and wouldn't take much time to implement. Probably ~2hr. Layout and aesthetics are more problematic if the same borders, images, symmetry, etc. are desired. ~3-4hr. If that's not as important and basic borders and "similar" layout is OK, ~2hr. Important considerations; 1. Many rpg systems track equipment, gear, resources, special abilities, etc. and many will require repeating sections. I'm not seeing those kind of sections in the sheet image other than the big open area under Skills. Is this just a large text area to handle those types of attributes or would those sections also need to be implemented? 2. Are there attacks with this system outside of just rolling stats and skills? 3. Roll template - depending on the system (ie the dice/roll mechanics) this can also take a little to a lot of time to implement. 4. Is this a known system or homebrew? Will it need to go onto roll20's repository? With that in mind, the cost is probably anywhere from $0/h (ie doing it yourself (<a href="https://cybersphere.me/roll20-sheet-author-master-list/" rel="nofollow">https://cybersphere.me/roll20-sheet-author-master-list/</a>) or finding a passionate volunteer or wanting the challenge/experience) up to $50+/h for someone that wants/needs to get paid for their skills. You might add a little more information to clarify what you would like included with the sheet. I'm sure I'm missing some things that other's may bring up... Cheers
