One place to get them from is here:
http://daydream.etowns.net/S2hacked.htmVarious iterations there, dependent on which EPs you may have installed.
Moving Sims into a residential lot without a mailbox and trashcan, and then finding no access to Live mode, but only to Buy/Build, is a symptom in some later EPs - so you almost surely used the cheat correctly and you just need to add the items, then all should be okey-dokey.
