Wtd:cheap large camping "tarp"(not a tent)-10mx8m-2colors green silver?

Wanted: cheap large camping Tarp -
I am talking about a "tarp" (not a tent)

Size of the "tarp" about 10m x 8m in two colors.

One side is reflective: "silver" or "aluminium" color.
The other side is "green" or "dark" color.

With enough grommets on the side of the "tarp" to attach the picket's ropes
and
enough grommets in the center of the "tarp"(sides) to pass the head of the camping poles.

The tarp on this Website looks good
http://www.dealsdirect.com.au/p/canvas-tarp-waterproof-24ft-20ft/
but this is too small, wrong colors and the material is not reflective enough for the Far North Queensland (FNQ) sun.

This "tarp" like my previous "tarps" will be used in FNQ under the sun, torrential rain, windy conditions.

In sunny condition the sides are up.

In torrential rain or windy condition I put one side of the "tarp" down.

I am talking about a "cheap" "tarp" ( not a tent)

Any cheap sellers -manufacturers- contacts - ideas or suggestions would be appreciated.
