Add Products Supplier module/block in product page

[CLance]

Hi. 

 

I done a products category module/block alteration in my product page.

 

However, I hope to add another module/block: PRODUCTS SUPPLIER, which will list other 10 products from the same supplier.

 

Anyone done this module?

or any guidance to make this done? I know something can be alter from productscategory.tpl.

 

This is my webpage for product: http://eviewtrading.com/denmall/home/1-ipod-nano.html

I modified from category module, add the new module and installed it, but it did not display in my product page:
