Does anyone know what reasonable compensation for blog setup and management would be? I've seen ads and information on what people charge other people to post, but not on setup and management.

Any thoughts?

Just charge by hour - the fee you'd normally take for doing anything related.
Just to make sure you don't lose time on setting up a blog for someone and be disappointed once its all over.

Charging somewhere between as much as you want but as little as you can afford may be it.
