At first i was thinking of using Magento but i am not so sure now as some of the features are missing which i need for this specific project.
@Pauli-d I am also a big fan of WP :)
@gecko Thanx, i did go to that website and it helped a lot.
During a meeting with all my team members we decided to build a custom CMS for this project.
Thank you all for your help :)
