Go to the island and catch palm beetles (Horned Atlas, Horned Elephant, Horned Hercules, Golden Stags, Cyclommatus Stags, Goliath Beetles althrough they're not really worth). Then sell them at Re-Tail and tadaa, you'll get lots of bells.

Island farming is the solution to all of your 'bellconomical' problems in ACNL!

Super hard, unless you stalk them on eBay and are willing to pay a lot of money. :c

But anyways, congrats! You have a really good map! And yeah I recommend everyone else's methods for making bells.
