Educational Website - Open Source Platform

I would also like a simple Educational Website using Joomla LMS, Moddle,Atutor or another similar opensource type of platform. This is a small pilot project as part of my thesis for adult continuing education classes. I already have prepared content for a Numeracy programme, but would like to test it by delivering an e-learning format. My target group are persons presently not in formal education, but would have at least gone through elementry education and/or partial secondary education. Hence the choice for platform should allow for some levels of interactivity. Website will have a home page, a sign up page, contact page administrator acceptance page Tutor login Student Login Virtual Classroom Administrators back end will need to be implemented with grades and scores for all students enrolled and for those who have completed the classroom. I would need the site ready for the first week in October or before that. Virtual Classroom will be accessible to both tutors and learners, but with different levels of accessibilities. Tutors should be able to upload learning content. Learners should be able to upload assignments. Course content is a 32hour Financial Literacy Programme made up of Four Modules. I would also like to add as a introduction.. a basic ICT module and user manual for the platform elected. Each chapter would be fitted with a time module, a user identification module and at the end of the module a test would be administered for users to complete with a set score target to be determined for a pass. Once user passes the score, the next chapter would open up and become availiable for the next user. At the end of the module, a predesigned Certificate tailored with the users name would be availiable for download in PDF format. I might need some learning material to be converted using Camtasia, to provide interactive content. The ability to upload information in word format and .pdf should be allowed. Site would need to be scalabe as more courses might be added to expand the test pilot project to use the same functionality. I would like to work with an experienced and fast developer... I have my hands full and this would be a very big help in getting the ball rolling. In your bid, please highlight similar sites developed and experience and time frame.
