Gab Goldenberg at http://seoroi.com/ http://seoroi.com/ did a little bit of free link building work for me (because I helped him with some other stuff), and he did an excellent job. I haven't heard from any of his clients, but he's active in the SEO community and often contributing new ideas. I've always been impressed by him. If I didn't do all of my own SEO work, I'd probably hire him.
