....can I go to to repair wood trim?

I've got a couple of wood pieces which are not just cracked, but chipped/gouged, and the wood underneath the veneer has been exposed. Probably about 4 square inches of damage. What types of places can repair this? Would it be easier to just do it myself with some sort of filler, veneer and sealant.

BTW - I've priced new wood trim, and it's much more than I'd like to spend on these items (~$325+)
