Magento

I will be building a mostly content-based website, where only 1 product will be sold.  The customer will need to go through different “stages”, or pages, before paying for their product.  Each page the customer should be able to upload a number of photos and photo descriptions, then move onto the next page.  There should be a progress bar at the top during this process.  From the admin panel, I should be able to download all images and image descriptions all at once easily. 

Can Magento do this?
