It's been almost a year since Sitening and I parted ways, and it was clear even at that time that their hearts were wrapped up in Raven, not in providing consulting services. My understanding is that, since then, they've been whittling down the clients they were consulting to, but this post declares services entirely gone.
Kudos to Sitening/Raven for taking a bold, decisive step to eliminate the chance for conflict of interest, or even the appearance of it. And of course, if you get good leads for SEO work, you can always refer 'em to [meta]marketer. ;)
