yeah
first how do you get published? you send in your oneshot to a publisher right?
& how do you draw a oneshot? normally, you would need a studio or drawing equipment and assistants
you can do that alone for a oneshot but for a series that's a different story
drawing 20 pages on weekly basis alone (can be done) but is very hard
