Chintzer
Someone who is only cares about money and prioritizes it over the work that they do. Stems from "Chintzy", which means cheap or stingy. Similar to a shyster, a chintzer will be quick to collect the full payment but your roof will be falling apart in no time.
I shouldn't have trusted that chintzer with my gutters, he charged me up the ass and they're still clogged.
