I tried Zookie Pro (design service at Zookbinders) in the first month or so that they were doing design, and found their work to be pretty good, especially for a service in such an early stage. I gave them an image set with about 20% more images than I wanted them to use, and gave them permission to decide which ones to use, and they made good choices; I approved the first design with no changes.
My design approach is different now (simpler), so I'm not sure I'll outsource album design again, but would consider using them again if I needed design. Layout isn't what I want to spend my time doing, and album design (i.e., the layout of the album) isn't something I emphasize; there's not a lot of juice to squeeze from that orange -- so I don't need to control it obsessively.
