More money than "her" would be the answer. She is used more when you use it at the beginning of the sentence. "she mowes the lawn." But when referring to a third party you would use her if she is the object, and not the action doer. We call these passive and active sentences. When a noun does an action it is active, in which case, "she is used." When it is a passive sentence, the object has an action done to it. Ex. The MILK is being SERVED. The milk is having an action done to it. This is passive. Hope this helps :) Remember: action done to someting else = her, the person is actually doing the action = she.
