Do not tell my sweet beautiful girlfriend that I spend way more than that on guns, and reloading supplies. I mean way more than that.
How much roughly are we talking for paychecks?
As for your list here goes. Based on my janitor's salary.
Concealed Cary would be a used Glock 26 9mm. Can be had in the area of $400 give or take a few dollars.
Birds, and small game Again a Used 870 Remington Wing Master I can find them at pawnshops usualy for a bit under $300. Also a used, or new 10/22 just to burn some rounds with. As for tiny critters like rabbits, and squirrels I have a pellet gun that kills them dead out to 80 yards so far.
Home Defense Same as CCW if I am afraid to defend my life with it inside my home, why would I carry it when I left. I understand the concept of having a full sized gun that one shoots better for home defense, though I would skip that cost and get an 18 inch barrell for the 870.
Deer and larger I am gonna go Used again with a used 30-30 this is Texas, and few of the places in this state that i have hunted have I ever had to shoot over 100 yards. Price usualy runs under $400 with a decent scope already on it.
