Reliable source for 80% lowers/jig plans?

[XWARPATHX]

I wanted to take a shot at milling my own AR lower and was wondering if anyone knows of a good source to purchase 80% lowers? I saw some on arms list but wasn't sure if anyone has purchased from their before? Also, I wanted to make my own jig for holding the reciever but have yet to find any plans. Does anyone know or have access for plans on making a jig?
my dad is a machinist and i wanted to find a few things out about his machines. Thought this would be a perfect reason!
