Not much we can tell you about what
YOU can hunt. We have no Idea where you live so don't know what seasons are open.
Saving money by hunting and fishing, now that is really funny. Maybe if you spread the equipment start up cost over many years and do not buy the latest and greatest you may save some money. Michigan Fire arm deer season for example you need a license, really two now. A base for small game even if you don't want to hunt small game and one for a deer. A rifle, muzzle loader ,pistol or shot gun and that is going to from 200 to 500 depending on new or used and scoped or not on it.
Then there is the warm clothing and boots figure another couple of hundred for that. Free to hunt on land to hunt on is scares here in Michigan during fire arm deer season, Ya lots of state and federal land but are swamped during the first week at least and you would still need a place to stay tent or motel.
If you don't know how or have the things to do your own butchering it will cost from 50 to 100 dollars for that and even more if you want sausage sticks made and other special cuts done.
Better to think of hunting as a reason to be out enjoying the out doors not as a way to save money.
After 54 years I guess I break even hunting, I drive 3 hours to bird hunt, 6 hours to deer hunt and can walk out my backdoor for squirrels, coyotes and even deer when I don't want to travel.
A cane pole from a lake or streams bank is probably the cheapest way to fish and you may save a bit doing it that way.
Have fun.
