don't bother with calling specific utilities companies. also to stretch that fence you can use a come-along, or a block and tackle. the block and tackle is easiest,you'll also want a bar with some hooks on it so it's evenly stretched,those are really easy to make.i have a block and tackle if you need it let me know.you'll also want a staticline around the bottom perimeter to tie to.makes it alot harder for the critters to get in/out.
edit: also the one-man auger will beat you up real bad, go for the two-man auger and get some help.they're cheap as dirt to rent from just about everywhere.
