Since 2003 we've kept ourselfs busy developing for the Content Management System Joomla (Mambo back then), mostly developing Components, Modules and Plugins.
Because of our experience as a techical partner for various advertising agencies, webdevelopment agencies and other companies we're very capable of translating your wishes into components and modules. We've developed an own programming library enabling us to develop for Joomla 1.0, Joomla 1.5 and Mambo without much modifications. We try to deliver the component installable and without making core modifications.
Please contact us and tell us your wishes. We'll estimate the amount of time required to build it and it's corresponding price.
Some of our components are available for free, please see our website: Joomla-addons.org.
