For recording audio and video, you can use your mobile phone if you’re on a budget. There are a few different options available for publishing your course. One option is to publish it on a free online platform such as Udemy or Coursera. These platforms provide all of the tools and resources you need to create a professional-quality course, and they make it easy to promote it to potential students. While not completely free, another option is to create your own website or blog and use that as a platform for your course. This will only cost you for the domain name and the hosting which can run as low as $5/month. This will require a bit more work on your part in terms of creating the content and setting up the website, but it can be a very effective way to reach students if you’re willing to market it. You can also create video courses and upload the videos to YouTube or Vimeo, which can be a great way to reach a wider audience.
