Just my $.02 from south florida,
Several years ago, i put in 1500 feet of field wire around some land sing my post hole digger on the back of my JD. After digging the holes, i nailed 4 8 penny nails in the bottom of my 3inch PT posts and then 1/4 to 1/2 bag of instant cement, then backfilled. I took the auger off the digger "crane" attached a boat anchor swivel and chain to the digger. Then passed the chain down through the center of the 330' rolls and put a cut piece of post in a loop of chain at the bottom of the roll so the roll was hanging on the chain and swivel. I could let out 50-60 feet at a time before i would stop the rotation to tighten up the wire. The wire was anchored at first by nearly a whole wrap around the 8" corner posts. I would say that while hanging on the chain, the roll was at least three feet off the ground. that would help getting a second row. Thank goodness i didn't need that!
The building code here outlawed stapled roof shingles--so pneumatic staple guns were dirt cheap. So, with galvanized and/or stainless staples, i could pin the wire to about one post a minute. It was amazingly simple/easy for me and my wife to finish the fence in about 4 days after work and with lots of breaks [i like breaks]. After 3 major hurricanes, it still stands.
The point is this field wire only keeps out the big stuff--raccoons and small dogs get right through. Have not seen a deer since we put it up. Have not seen a bear since we put it up. I have seen bobcat and panther tracks though--or some really big house cats!! No wild pigs either.
Also. we put up 2 x 4 welded wire cross fences to make separations. Squirrels go right through. I've had to cut out 2 rabbits who died trying to get through. Rabbits don't go through and quit trying after the second death.
The welded 2x4 is now rusty and needs to be replaced. When it gets hit [like with a brush hog, it will break in sections. We're not happy with it at all and decided that the replacement will be galvanized hardware cloth--more $$, but will outlast the 2x4.
good luck with whatever you do!
