By personal experience the best ways to make in game bells in order is:
10. DLC: DLC is very common on wishlists. Especially foriegn DLC.
9. Assesed Fossils: People are very impaitient and want these because the will help with the mueseum
8. Guliver Items: Guliver only appears once in a blue moon!
7. Silver and Gold tools: These dont just sell well, but for a lot of money
6. GracieGrace Items: These are popular because a lot of people don't have Emporium yet
5. Works of Art (Legitimate Ones): These are basically for the same reason as assesed fossils and silver and gold tools.
4. Complete Sets: Not really bestsellers but worth a lot
3. Fireworks Items (Lovely Phone Especially): These are worth a lot and sell almost immediately after put up for sale.
2. Hybrid Flowers: Everyone likes bootiful flowers, especially the valuable ones
1. Picture of Villagers. I don't know why, but everyone is OBSESSED with these
