Trigger question and stuff

[Nanchaku]

Hey everyone, I'm not sure if this question has already been posted so I apologize in advance:

How do you make it where when a specific building is created that it'll periodically give you money overtime?

Also, I am working on a map named "War of the Crusaders" it's a melee naval map with a bunch of junk and I'd like to have someone as a partner.
