you have to write a novel 60000- 80000 words and there's all sorts of factors that are important to how well that novel sells
cover art, blurb description, first five pages, the story itself, the title!

And don't forget that if you don't spend multiple years to get a major publishing office to take the novel you spent multiple years on, then you'll never ever make any money from anyone ever. Or get it into a store. Or actually have someone read it.

The most important factor in how well a novel sells is absolute pure chance. And your name. Which nobody has ever heard before, which is not a good thing.

(But yeah, you really can't put up 4500 words. As good as those words may be, if you don't have a novel-sized book, people will just kind of scoff. I'd suggest submitting your work to a magazine, because that'll let you take approximately less than five years to do)
