Heres how i get money.. but it takes about a whole (in-game) day to do it:
Buy a large area of land and make sure that the soil is fertile.
Then follow the instructions to make some easy money
Spring: Buy 9 Breadfruit seedsand till an area (this is hard to explain) uhh... till 4 rows of 9 going vertically skipping every other space. Ok... then starting on the top row fill in the spaces of the first row then skip a row... then fill the 3rd row's spaces... in doing so you have an area to jump around in. then plant the breadfruits and water them every day until they grow big. then harvest them. but you cant get into the middle breadfruits from the outside so you have to jump over the crops to get into the inside. After they grow to their biggest they will come back every other day if you harvest them and water them on a regular basis. If you did it the way i did (sorry if i didnt explain easy enough...) then you should score over 20,000G every other day...
Summer: Same thing as spirng excepth use corn
Fall: Same thing except use eggplants
Winter: there are no crops during winter so do what Hopey_Dopey_13 did and gather as many jewels from the lake cave every day until you get the amount you need...
Sorry if i couldnt explain that well enough... thats probably the best i can do...
