Plenty of people consider the $5 or lower pricetag to be someone's bad game. As for the amount of sales you'll get? On itch.io I've only received 1 sale from someone I didn't know and that was a donation for an art pack. Beyond that I've made $8 in a year of being here from 2 generous people I know. I hate to be a wet blanket, but that's my reality that you might be walking into.
You have to publicize and keep publicizing. Draw people in. I think out of 3 games and 1 art asset pack I have 1,500 page views and maybe 400 downloads.
