Oh well. You can't really be helped if we don't know your abilities. There are people who make money from scripting or mesh - the point is, you have to be really good, the market is filled with excellent builders. Many also offer custom work, for example for shops. So as long as you are not very good or have a revolutionary idea that hits like a bomb, you will hardly make a lot of money in this area. The same goes for textures, photography, ... the competition is very high.
Then there are clubs that are looking for a good DJ. Here, too, "good" is the point. Clubs that run very well do not take everyone, often not even beginners, but prefer well-known DJs with a fanbase who can also come along if you understand.
Hosts, dancers and escorts are hired a lot. To do this, you have to have a handsome avatar, completely mesh, sexy and up to date. You have to be able to entertain the guests and approach them without being intrusive. Unfortunately, it is still often the case that dancers play an animation and hardly say anything. You won't get any money this way. likewise when the club is not going well and no guests come by.
