Get real, there are really so many free and better Models available online.
Even If you charge 1$, this is even more work to do the purchase
than just looking for some free model.

Try to create a selection of Models, that have a common theme and look.
For example a set of Characters (Man, Woman, Orc, Dwarf, Elve) and
Models for Weapons and Armor for them.
Then this collection has a value, as it covers a certain requirement for
a gemadevelopment (getting a set of characters and items with a consisten Style)

Better you train your modellingskills before trying to sell the work,
rather donate it to a certain project.
