Highend Custom CMS Development

Looking For Established CMS Design Firm

[kindred1]

Hello,I am researching companies that offer Highend Custom CMS Development for a new version of our site in the future. Im having a bit of trouble locating firms with high profile CMS systems in their portfolio. Anyone have any suggestions or links?

Our site averages around 400,000 uniques and around 900gb bandwidth monthly and growing. We are at a point where we want to switch hosts and get a more robust server system and start planning a cms for the near future.

thanks for any suggestions.
