Plans For Sheds

Instead of building a big wood chicken coop…I want to just buy a shed/garden storage, and convert it to a chicken coop…so where can I find the best deals on them…I can’t afford anything over 00, and preferably not over 0. Has to be atleast 8′x8′, pressure treated wood, sturdy, etc. I’m in Charlotte, NC

Thanks
I don’t like any of the chicken coops online, they are way too small, & have little or on access. I want something kind of like a mini barn…so that I can go in their with the chickens & I want to store their food in their.
