Bench Seat Reupholstery

So, I bought a 70' duster and it has the original rear seats and what looks like a c-body front bench seat. What I am trying to figure out is if anyone has some cheap home-upholstery tips or easy ways to fix the seat without using seat covers or a band aid fix. Cheap as in $50-$150.

*all the quotes I got from the upholstery shops around me were way too expensive.
