oscommerce model search

I need a bit of code written. I have an oscommerce store [login to view URL] . It is a book store with the title of the book and also the author name. The author name is based on the model_number. On the example I have given it would be E W Kenyon. What I need is to make the model_number (E W Kenyon or other author name) a hyperlink so that when you click on it it will do a search and take you to all of the books that have been written by that author that is on our site or in the database. Here is an example of it at this site: [login to view URL] notice the author name Erin Hunter and how when you click on it, it takes you to all books by Erin Hunter. I want the same think on my site. I can insert the code. What I need is someone to write it for me. Thanks Leon
