Aluminum plate light easy to cut and strong enough for what you want to use it for.

I have seen new welding clamps like this for $5 at the flea market with a vice grip mechanism.
How hard do you want to clamp?

Thanks, I want these clamps for woodworking, I do live in India where I do not have much options to either buy online wooden clamps or from nearby market as these hardware shops are selling only basic tools like screw drivers, saws etc. Links for online shopping for clamps are given below, these clamps are too expensive and so small that these are not usable in wood working.

I would actually suggest making the first model with corrugated card, just to get a feel for the "right" sizes.

The clamp will not work if built as it is depicted in your drawing.
The bolt in the handle above the cam will prevent the cam from working.

Here are two links , so  you can get some ideas:

You are correct, I have to modify clamp, thanks. The links you have given shows clamps without flexible jaws, which may have problem of applying pressure only at the edge and not across the entire face.

Depends on what you want to clamp and how much pressure you want the clamp to clamp. Materials range from plastic, wood, metal, you could use strong enough flat stock or design in reinforcements along the jaws and handles.
