Louise and I don't put our shade over our tent, but we aren't in the tent during the day. We've got some shade articles here:

but none very recent. They tell you how to make several different styles of shade.
We bought a shade set up online - we got a silver tarp, two side flaps, and all the bungie cords, then bought the poles at our local hardware store (it uses cyclone fence top rails cut to particular sizes).
We also made our own shade from scratch from rubberized canvas, fabric pieces, and EMT tubing (yeah, EMT tubing is like Rio Grand River, but if you don't know, you need to know it's tubing).
To get good answers here, you need to tell people any limitations you have in transport. Our longest poles are 10 feet long cyclone fence poles. Can you carry those? What about six feet of EMT? Or PVC. Have you got space for a huge tarp folded into a large cube?
Are you flying in? Driving? Hitch hiking?
