According to this new post on his blog Stefan Priebsch, Sebastian Bergmann and Arne Blankerts have joined forces to create thePHP.cc, a PHP consulting group.
In times of tight budgets, quality is a key success factor to reduce
risks in IT projects. [...] We help businesses and enterprises to reduce IT costs in the long term with Open Source technologies and PHP in particular. We support our clients in improving their employeeâ€™s qualification to overcome skills shortages.
You can get more information about the group (including conferences they'll be at and contact information) from their site - thePHP.cc.
