The most important way to find the right money making ideas for you is to evaluable your market and customers. You need to find ideas that you can put to practice and know that there is demand for what you are about to sell or provide services for.
For example, if everyone in your town has a dog or two and there are few dog walkers in town, a dog walking service could be valuable. You need to ask around to see if anyone will hire you if you set up that service.
If the answer is positive then it is a good money making idea for you that will also help a lot of people.
