There are 3 main ways of making bells that I've seen in the games. 1st is time traveling for bank interest. I've never liked that method. It was way to much of a cheat and the weeds where terrible. 2nd was the turnip market. That may be fine for some people, but I didn't like the chance, so I rarely bought more than 100 at a time (if I bought any at all). And 3rd is foreign fruit orchards. This is what I usually did. Of course New Leaf brings new possibilities.
Native fruit is worth 100 bells. Foreign fruit is worth 500 bells. Delicious native fruit is worth 600 bells. Bamboo is worth 750 bells. And finally, foreign delicious fruit is worth a whopping 3,000 bells! Now unfortunately, foreign delicious fruit will not grow into a delicious fruit tree, but if you have friends there is a way around this. I don't know why I haven't heard of anyone else having this idea, though I could have just missed it.
48 is the perfect number of trees for this. 9 fruit in a basket and 16 spots in your pockets. Plant an orchard of native delicious fruit. I know that they eventually wilt, but just replant them afterwards. Every 3 days trade a full pocket of delicious fruit with your friend for some delicious fruit from their town. That is 432,000 bells every 3 days! You can take it further of course but that alone is amazing.
