Cs Multivendor Cart Modifications and add ons

Hello, I have a CS Cart- Multi-vendor installed and I need a few customizations. My website sells downloadable e-books. I need the following: 1.) Need the vendor name that appears under each book to hyperlink to the vendor's storefront (should be pretty easy to do this). Right now the vendors name appears but it doesn't hyperlink. 2.) Need a flipbook style magazine installed to show up for each product. The flipbook will show pdf files (a sample file with sample pages of each book) that have been uploaded by each vendor. From the vendors products panel they should be able to simply upload their preview file and then when that product is viewed live on the site the flip book should show the file. You can see the CS Cart Multi-Vendor at this link: [login to view URL] If you can perform either both or just one of the above mentioned please let me know. I would prefer someone who has experience with CS cart, but this is not a must.
