Indiana gardner in search of a good deal for a 100' walkway

Looking to do a long walkway in our backyard. Looking for a dealer who can sell us stone so it won't cost more than $300. We are flexible on what type, so long as it's consistent (light gray to blue-gray is ideal), and most importantly, cost efficient. We have access to 3 pick-up trucks, so we may be able to do the hauling ourselves (unless this is not enough).

We're about an hour from Indy and 2.5 hrs from Chicago in Indiana.
