Module to Show each Vendors Products on their Link

I have been trying to figure out a way to show the vendors products on their page when someone clicks on their name. I was trying this by making each vendor a category (ID) but even if I could get it to work, it would get extensive if you have many vendors. A simple vendor product module that shows only items from that vendor might work? The module could use the vendors ID so all products from that ID would be listed on their page.

i think its must look something like Vendor=Manufacturer=Vendor all items

when you click on vendor info you can see all him items like "manufacturer"
example: you open info some vendor and want see all him items for that we use vendor_id like in manufacturer filter we open for example Sony where see TV,Laptops,Cameras etc
