Well.. Adding the skilling would be hard. Adding the teleports/commands will be 4/10 for difficulty because it takes time.
Work has its' rewards; having multiple spots also encourages the user to explore more areas of the server, therefor creating more time spent on the game - rather doing everything within an hour.
Goblins
Al-Karid Warriors
Rock Crabs
Hobgoblins
Lesser Demons

Many places can me implemented, and teleports can be as simple as to talk to someone at a specific location. Always have the Home Teleport in case of need to return to base.
