Visio Shapes needed for Linksys, Netgear, and DLink

I am trying to complete Visio diagrams for some of our smaller clients that use Linksys, Netgear, and DLink for there network equipment, KVMs, etc.  I only would need a very few being that most companies like Cisco, Dell, Sonicwall, Barracuda, HP, etc I already have.  

Any assistance to free shape downloads for these lesser equipment brands would be greatly appreciated.
