Hello! Sounds like the easiest thing, though not the quickest, will be growing and canning your own food. The bush survival skills will always be invaluable, I think the compound bow is an excellent weapon to have, I plan on adding those and a crossbow to my small arsenal .
Would be keen on a crossbow but local laws make it impossible to obtain such weapons. I have also looked into getting a gun license but the steps to undertake such a task out way the benefit.
