I know of ways to get money, quick! {in multiple seasons too!}
Spring:
Go dig in the cave by Jamie's house and sell the findings, in summer, things are worth more than ever! [FROM THERE!]
Summer:
On some days, there will be oranges, and they are worth 200-400G |of course if you hadn't cut the trees down!| They are found south from the blacksmith's shop, southwest from the lumber shop.
Fall:
The crops MADE BY YOU will be worth a bit more, probably 200-300G, for me that is...
& Winter:
Go to the fishing spot where you found Ray/the old man, and walk, yes: walk, on the water, actually ice at this point, and go into the cave, make sure you have a Hoe AND a Hammer, if you use the hammer, there will be mostly athremyst ( I think that's how you spell it ), Sapphires, (Rarely Rubies), and other things that I can't remember, but have the blacksmith to make them into rings, and they will be DOUBLE the amount of money you paid for them!
