Obligatory novel not a comic, but...
First thing I would do is give myself a salary so I could quit my job and work on this full time. Then I would hire an entire marketing team to promote it for me (I would want to sit in on meetings though cause I admit my floundering efforts at self-promotion have made me kind of interested in what it takes to actually be good at this), a couple of editors, a couple of artists to do covers and banners, ads, etc., and I would get to spend all my time doing the actual writing and revising.
I used to think being a writer entailed mostly writing. Boy was I wrong.
