Casino Pixels

I want a very simple wesbite. It will function like this ---->> [login to view URL] and also look simple like that too. I want to divide the square into 4 smaller squares, because I want to put the logo in category. I will add a sample. I want to be able to easily add a logo of a customer (company) anywhere in pixel field using a simple system. You will need to create a Site Management for me so I can add, delete or move logos easily. There will be around 8 pages, but only the main page will be the imporant page, all other pages will have information only so you dont have to spend time on the otehr pages.
