CMS - Documentation site

Hi, I would like to have an offer of you for the following application. I’m a Belgium refrigeration technician and we use a lot of technical manuals. We share all those now amongst each other via our website [login to view URL] just by sending those to each other. I don’t know if all the following will be possible to program. I will fire my questions: I would like to set up a database of technical documents (mostly pdf and doc) and pictures. Every registered member can upload new documents in different sections and subdivisions (for example cooling, subdivision thermostat, subdivision electronic thermostats). New members must register first to avoid spamming. New documents can only be entered via an antispamcode Possibility to search for members. Actual members on-line and their name. Statistics who downloaded and uploaded documents and how many/day, this showing on the main screen. If possible, a limitation/member to avoid that someone downloads the whole content of the website at once and increases bandwidth to fast. I was thinking of a daily limitation and/or weekly limitation/member. Eventually a system like some P2P’s have where someone gains download credits when he uploaded files to the server. A poster must add search tags to his document/picture so that it can be retrieved easily by others. At least two or 3 tags must be added so that they do some efforts to make their document searchable. The servers remembers who uploaded the documents, for example a message ‘This document was uploaded by MisterX on 12 june [login to view URL] uploaded already 120 documents’ Moderators must have the ability to change or add search tags, remove unwanted files. Some publicity space so that wholesalers can add their logo’s to the main page or the pages belonging to their section. For example, when someone searches for Mitsubishi, the Mitsubishi logo appears somewhere on the screen. It’s not my intention at all to gain something with this website, the idea is that the wholesalers pays just enough to pay the cost for hiring the webspace and the price for the programming spread over some years. If I ask only 20$/year/wholesaler and I find 10 wholesalers which will help me then most will find this a small amount for free publicity and my costs can be paid. If a German member connects, then it should be of course better that a German wholesaler appears on the screen. So if someone searches for Mitsubishi manuals, the German Mitsubishi wholesaler appears on the screen. I already have some moderators which will help me for free like we all do at refrigeration-engineer. But again, the main idea is to provide a general free database for all my colleagues and make some publicity for my small company (me and my son) worldwide. Many don’t even have the possibility of broadband (South Africa and in fact most of the African countries), can’t even use Google (China) So, think once if this is possible
