Hi @Veasna, M. - welcome to Udemy. The first task is to go to Udemy and search for courses in your area of expertise. Then go to Udemy's Marketplace Insights (under tools) and you will start to get an idea if it is worth pursuing.
It is important to do the groundwork. Really study your competition, watch all of their preview videos - see how you can make a better variation, or how you can stand out. Read their CLP's, make notes on their course images.
If it is a crowded area course wise - ask yourself "what do I need to do to stand out".
If it is a niche like the one I teach - ask yourself "how am I going to attract new eyes (potential students) to this subject area"
It is important that you produce the best course you are able to.
Good luck and enjoy the process
