Check with the arborist (tree trimmers). I've had nicely trimmed pieces and mulch put right in my front yard just by asking when they were working on my neighbor's trees. Also, keep an eye on the curb - I've gotten nice sized pieces from the church when tree there were trimmed and often, if your neighbors trim up you can get wood right in the area.
I have a stickburner so larger pieces have been my scores..but it you are using a smaller cooker with chunks or chips you can really do well with trimmed limbs and cut them into chunks with a chop saw.
