Wanted: Seat Covers for Dodge mini van

I'm buying a used '88 mini van from a family member. It's been kept in the garage so it's in good shape inside and out. Since I would like to keep it that way, I am looking for seat covers for all seats 2 buckets, 2 seat bench, and 3 seat bench. Does anybody know of any good companies or how to go about making your own? I can't see me buying from Wal-Mart, they look cheesy and flimsy. Thanks.
