Youtube has always been a good way to earn money, but not when you're just going to start today. A lot of people are already famous on Youtube. The competition is just too much. You'd upload one video, and then you'll see a similar channel uploading the same thing but have a much better quality content. If you're going to do Youtube, do it because you like it and you enjoy doing it, not because you want to earn money from it. This is true in blogging as well.
Selling your services, on the other hand, differs on the forum that you're going to offer your service. If it's here, then there are already some that are known here for certain services. Always look at other's work only to see if you can compete with them or not. If not, then just continue practicing and maybe do some small time service just so you can still generate income while practicing.
