Materials Packs

I was working on a few test textures for a system I'm working on the other day and I noticed that it didn't take too long to get three nice looking sample materials, I've been working with different tools for making decent textures and by extension materials for a good while now and I was wondering if anyone would consider buying a pack of 30 materials to help support a project I'm working on.

So the question is would anyone here pay $5 for a pack of 30 materials?

I'm thinking the split would be:

10 Metal

5 Plastic

5 Organic

5 Effect

5 Requests (first five requested materials)

I understand that it's not difficult to make procedurally generated textures and the normal maps for them, it's just something I think might save people a few minutes.

Some examples:

 

Sure, sounds good.
Perhaps something leather or glass? Mobile ready would be handy as well

B.

 

I think someone already created a glass shader (I'll see if I can dig that up for you) but I can try leather.

Edit - A simple glass shader resides here

I'd like to make custom shaders but I'm not far enough along in Cg programming I'm afraid, so I'll just be providing textures using Unity's built in shaders for now for now.
