Thanks a lot!
The lamp posts I picked up off of Ebay a few years ago; I think I got like 50 for super cheap (can't remember exactly as it's been so long). I'm sure that they, or something comparible, are still available - search HO scale lamp posts, filter it by lowest cost plus shipping and I'm sure that you'll find something that works for you!
They actually have working lights in them, though I cut the wires for my purposes
