Don't call unless they are way out of your town! GO, be there in person, buy a cup of coffee and hang out. People like the personal touch!
So many folks call then never show up. (I've been in & out of retail all my life)
But be sure you can sell them on the idea that you can supply them an unending supply whenever they need it!
I bundle mine in a tire with my daughter, some have small wood and some have up to 4" rounds for those who want a lasting fire. I try to toss in a couple pieces of pine or hemlock with the 'smallwood' bundles.
We sell to people at the campgrounds because they are just over the hill from us and have to drive by.
We also sell a lot in the winter to icefishermen! Start by selling from your driveway and ask those people [friendly] questions, then customize your biz to their needs.
Oh, and when you go, make sure you have a pickup load of bundles, you never know.
