Unfortunately, I don't think there is a cheap option. I tried to make mine as cheap as possible by putting in 8ft angle iron posts. On the bottom 3ft I stretched a stiff wire netting (more expensive than chicken wire
) to use a rabbit fencing.
For rabbits it's necessary to bury the wire about 4" deep and the bottom part needs to be at right angles to the fence and on the outside of the fence. Rabbits try to dig under fences but tend to only do it right up against the fence.
Above that wire I've stretched chicken wire but not tried to make it perfectly tight. This only has a minor effect but if a deer tries to jump the fence and doesn't quite make it they sometimes try to scramble over the fence. If it's not too tight the wire just bends and moves around a lot.
In addition to that I use a very old time deterrent. Apparently deer dislike the smell of soap and the plainer the better. Not any perfumed types. I buy big bars of the soap, cut them into 1" squares, put them into muslin bags and hang them on the fence - about every three foot. It seems to work and the soap lasts a whole season before it melts away.
