Most cost effective source for residential wire and conduit?

That's wild. Ya I'm 1000 from the road, and he is 2000. Did you bury that cable?
Pulled it through 3/4" poly pipe, along with a 14/2 direct burial low voltage cable just to make it "fun" in case we needed some DC power later on. I had the 7000' spool of it, so while we were pullin... lol Then a porcupine decided it wanted to chew on the plastic pipe, fiber and wire and his internet went down... so we had to run a ditch witch machine through the woods and bury it all.

6 "wire" fiber is only about 20cents a foot.
