Odd jobs can include anything from garden work, pet care, clerical work, cleaning and other short-term tasks. Depending on the task, you could be working for a few hours or a few weeks. During your spare time, search for new clients, negotiate the price and tasks involved, and schedule appointments. Customers expect reliability and, in some cases, rely on your knowledge and experience. Like any job, if you're working an odd job, you must be committed to completing the project from start to finish in order to be fully compensated.
