help site customizable in content. CMS - maybe joomla

Ladies & Gentleman, we do need an own help site just like this one here: [login to view URL] We will forward you a customized design. We want a complete help site where we can change every text scipt & even launch different sites in different languages. So the site must be fully text customizable. We should be able to: - add new main category - add sub categories to the main categories - add html text into the main description - prepare the indexpage (most important questions) - Add RSS - Add stuff on the left site (under the categories) It should contain: - search possibility. Search through our content. - "Was it helpful?" bar under every description within a subcategory. You can program the site in PHP / ASP / JSP or whatever you like to - as long as it is working. We would suggest you to work with a cms. Maybe joomla. Please don´t simply bid but: - tell us what experience you have in your language - tell us how you want to realize this# - the more you write about the idea you have from this job - the more we believe you know what we want. We will pay you out once the whole job is done and once my programer tell me that everything had been done accurately. We won´t pretransfer any money nor use the gaf escrow system. We do first want to work with you in order to assure with whom we are working with. If you don´t accept this conditions - please don´t bid. We are looking for a long term work ship. If we get to trust you we will also give you add ons to work on our projects. best regards Daniel
