The fastest and easiest way to earn money in CityVille is to always have a supply of Goods. Keeping business supplied will yield huge amounts of money. the trick is to have a Very large farm, taking up about 1/5 of your total land, that includes both fields and storage. The advantage of a huge farm is that you can organize it into different zones for different crops, ensuring you will always have a steady supply of crops. your farm should grow as your city grows.
