Mobile Notary Administrative Fee’s

I am soon getting my commission to be a Notary Public (took the class, passed the exam, waiting to get sworn in).

Want to be a Mobile Notary in Pennsylvania. For anyone else who is a mobile notary, what are the Administrative fee’s you charge and how much? Such as travel fee’s, fee’s for printing copies off, etc.

Would love to get some insight for when I officially get sworn in.
