Let us go fishing for money
Small fish = 5 - 15$
Medium sized fish ( 5lbs+ ) = 20$ - 30$
Large Fish ( 10+ Lbs ) 50 - 75$ ( rare )
Insane Fish ( 1/ 275 chance or sum ) 250$ - 400$

( the size system could be different but fishing would be cool in general and you would need a license to not be arrested for illegal game fishing etc )
