Think about it this way . your are making money out of something that will benefit the whole party. your group is right !!!! If your charging them for a creation of items why cant they charge you for other services..like you mentioned...why should they heal you unless you pay them? they could've just left you to die when you need help and just loot of your body.
and trust me your group is mature for not doing anything to your character.since im pretty sure everyone will be pissed by that kind of item creation policy
