Yes, got pretty good results with the brpadcast method on the wildflowers. Didn't lose as much to birds/turkeys. As the wildflower seed is pretty small, the roller pretty much got them into the ground.
As for the sunflowers, I spread the planting out over a two week period. AND most importantly, let my 2 daughters help out (11 and 8). When planting the sunflowers, I don't hoe rows or furow them. just lay a string to keep rows straight, then hand the girls 2 walking sticks which are painted on the end. they drop a seed on the ground and push it into dirt until the paint can no longer be seen. Of course, I get to help out too.
Does take as long as you'd think. When this years patch comes up, I'll snap some with the digital cam and post them on here.
I was amazed just how fast deer can clear cut a sunflower patch though. But since the sunflowers were for the critters to feed on, didn't mind too much. As a side note, out of curiosity, I also took about a half acre plot and used 'sunflower seed' packaged as bird seed to see what would happen. I broadcast it, then ran the tiller over it (set to about 2 inches)..Believe it or not, most of the came up/bloomed, but very small plants.
Good luck!
