243163 oscommerce customisation

I have an existing oscommerce store that requires some modifications, these are as follows - 1. I require a new store header, this header will be in two halves, on one side will be an image. On the other side will be an area for text. The image will fade in and out between a pre-defined selection of up to 8 images (images are to selectable and uploaded via the admin panel). There will be 8 images for each category (plus one for the information pages) so going to a new category will display a different selection of 8 images rotating. Image size/formatting will be done off-line prior to uploading. Must be able to add new images for any new categories created. 2. Text - text editor for the above text area to be added to store admin, the store already uses fckeditor so this should be used to add the text mentioned above for each set of category images and the information pages images. Also to work with new categories created. 3. colour/layout change, for each category/subcategory visited (currently 11 categories) the faded background and colour of the info boxes will change to a predefined colour. Ideally I would like to able to control this from admin in case more categories are added in future, tho not sure if this is possible or feasible, please advise if your bid covers this to be included or not.
