4. Teaching - Offer basic training courses or seminars for those who want to learn more. You can opt to charge a minimal amount for attendance to make an extra few hundred dollars every month. This also is a great way to get new client leads, people attending are likely to pick you over anyone else to help them with their project. You could also offer individual training for an increased fee. This again improves revenue and builds a contact base of people likely to recommend you when a "big project" that is over their head comes along.
