How can I display seller info with short description on it's product page with a link of "View More Info". On click, the user can get redirect to the seller profile page. This would really help me out guys! thanks in advance.
I would say an ideal solution would be to create an extension with a new "seller" entity type, then have an attribute on products linking to the seller entities. You could then build a new page based on the seller data and automatically link to it from product pages. Depending on your level of Magento knowledge (and available time) this could be quite a task.
An alternative approach could be to create a CMS page for each seller and then add an attribute to products linking to that CMS page. Its not as elegant but would be much faster
I'd guess you'd need to create custom product attributes and alter the design so that they were encapsulated into one area that you want them to be located in or one tab. And some information on adding custom tabs to a product page can be found on this StackOverflow question.
After that you just need to customize the CSS of the theme to display it how you want, then create the page somehow for the seller profile. Either static pages, or possibly some blog system to accomplish that part.
