Article about 3D virutal reality worlds

We need a proficient writer to write an article about Second Life and its possibilities. The article should be descriptive and giving a good idea of what users can do to create their world. Besides general description it should also include important technical data, for example system requirements, scripting etc. The article should be written by a person familiar with different 3D software products as it has to include other 3D software products that allow users to create their own space and which might become competitors of Second Life. We expect to have at least 3 different products described. Length of the article should be about 3-4 pages, which means about 1500-2000 words + several pictures of different products and possibilities. Language of the article is English and we expect it to be written by a native speaker. Upon completion of the project, complete ownership of all parts of the article with complete copyright shall be transferred to us. We will have exclusive right to edit, format and use at our discretion. You agree not to resell or reuse the article.
