Design Badges

Has anyone ever sold a badge design to a large company, and what did they charge – its my 1st deal?
and I don’t know where to start, so I do not get ripped off, has anyone any examples?
paying a legal bod may be more than the deal’s worth – its only a one off thing.
Simple.
Decide how much you want to be paid per hour (or day etc), work out how long it took you to do, and charge accordingly.
By definition, if you are happy with what you get in return for your work then you are not being ripped off.
