Sharepoint Document List web part view customization

We have 3 pages with standard SharePoint 2010 document list web parts listing a selection of documents in the given folder in a standard SharePoint list view - we would like to style the page so that the documents appear in a 3 by 4 array, where little thumbnails uploaded to an image folder could be used as thumbnails for the individual documents - the user must be able to slide the content of the array to display previous and next set of thumbnails (according to the number of documents in the web part list) - the page should also have a set of 3 or 4 filters to fine tune the listed documents in the list, so each document might need a couple of categories to classify them by. We will require 3 variations on this page where the only thing that changes for the 2 subsequent versions are the filter buttons - the rest would be functionally, exactly the same. This work needs to be completed for my customer's intranet pages and I cannot share any detail of the job until the successful applicant gets the job - there is an existing budget for this job, but i would like to discuss your availability and when you think you could have this done by as it is quite urgent - only then can we talk about budget. thank you for showing interest in this project and hope to deal with you soon - Barni
