Keeping your chain sharp is a necessary chore if you use a chain saw.
You have two choices. Learn to sharpen one yourself (it isn't that
hard) or take the chain(s) to a shop and pay them to sharpen them.

A couple hours use is not out of line for needed a touch-up. There are
no "high quality" chains that will last much longer especially in the
hands of a beginner. You can get for high bucks chains that are
carbide tipped but even they don't last forever.
