Updating or porting an existing mod to a different Minecraft version, mod loader or dependency set, fixing bugs, implementing changes, support during a stream or event (1 hour minimum)
These are starting points and I'm happy to negotiate. Version prices especially depend on how much the game's code changed between versions, not on the version number: some major updates mostly add content, while some minor ones rework the internals.
