deer can jump an 8 foot fence unless you wire string with ribbons the top using any terrain change near the fence to get in we use a 12 foot fence 2 feet into the ground and ten feet up around garden and animal barns. we use chain link. depending on size of fencing job you can get it cheap from china if in bulk.. remember to cement all poles in and use good quality galvanizing.
the fencing rolls are very heavy so doing this manually is unusually hard would suggest renting a tractor with a fencing spool. and an auger to dig the holes. if your soil drains or is dry enough do all the holes first. then cement the poles once done then put up fencing.
you can also find it at military surplus sales locally
then again i live in wild territory where we are in their space not them in ours.
