Hi there

"What to charge" is always a really big question, esecially when you're starting out. Unforutnately no one else can tell you what to charge, not only because it must be based on your own exerience, skills, etc. but because to have a public conversation about rates for a particular sevice is frowned upon as price fixing....
With that said, I'd suggest taking some time to look at websites for other freelancers who offer the same service, and check out what various VAs charge as well.

I charge the same per hour for the services you listed as I do for any other admin task - aside from printing which often carries third party costs that will be charged to the client along with the hourly rate.
Hope that helps!
