You can't do all the work that's needed to be done because it's literally impossible for a human to do all the needed work. There are many fields which require educational background and experience and everyone can't just do those type of work. The only work you can do is the skills that you have acquired either via video tutorials or via practicing those yourself.

It will be better if you share some of the skills that you have and you should also try to share some samples of your previous work so that the client may pay you for your services. If you are good at programming then surely you may get programming related work and if you are good at writing then you may get clients who are looking for writers.

Additionally, you can also try your luck at freelancing sites as there are so many clients who want to have their work done by a freelancer. There's literally need of work in every field but they need only those workers who have the skills to do the work according to their specifications.
