I have to agree with Ross Rave, a pig can work wonders.
My advice is to plant trees that are higher than the weeds.
Cut down the weeds and let them be, nature does the rest.
it keeps the soil humid and eventually weeds will stop coming.

Anything whith thorns will keep deer at a distance,
in old british landscapes they used to make hedges by bending and weaving thornbush.
A shitty job to do but it works.
Sometimes with an edible fruit or tree growing in between the bushes.

Another option is sepp holzers bone sauce, it keeps most critters and deer away.

Basicly everything can go to the chickens,
Bones could be used as fuel for fires.

Just keep in mind that most pests are bug-sized, witch means predators like coyotes are not that useful.

My advice is to attract beneficial insects and birds that feed on lice and other pesky bugs.
Rabbit problems are easely solved with an airgun. And they give exellent free-range and free meat!
