!!help needed material locations help needed!!!

Hello everyone. I have been tremendously humbled and intrigued by the knowledge on this website. This is the single best forum i have ever signed up for on the net in my life. and computers ARE my life. So with that said i just want to say thanks in advance to all of you and ask some simple questions. I have decided to go Aeroponic and DWC/NFT hybrid b/c im facinated with the approach and i sent back $500 worth of drip system equipment that i felt was archaic. I see now that the Seemorebuds video - although extremely educational - was more about promoting the kick ass system than anything else. I would order one but i know i can build one for $100 that is possible even better and i have heard they take FOREVER + 1 day to get the system shipped. i have found an incredible resevoir and have alternative materials if i need them. BUT, i need help locating a material that will work well as the top in my aquamist style system. I found some light weight sheets of corrogated plastic but they dont appear to be strong enough. I am just out of ideas and there is no where i can ask these questions in public ya know. So i thought i would ask here in the DIY forum. I need something i can cut to custom dimensions to fit over the huge cooler i found and make a top for my net pots to go into. i have seen plenty of things that will work here on these forums but i just dont know where to get those materials. And the Home Depot and Lowes in my town suck ballz. They dont even have the little red 360 misters that we all like to use.
I also want to ask you all what you think about Pop-up sprinklers. i purchased a few of them to see how a system will work, but this will be my first grow and i cannot afford to mess up the harvest, i wonder if the pop up sprinkler will be too strong and slice the roots or something? anyway those are my questions i appreciate any help. im long winded so let me restate.

Where can i find plastic sheets or something comparable to make my aquamist style tops out of?
Where might i find a tote, resevoir, or container similar ot the one the aquamist uses?
Do you all think that pop up sprinklers will work in this sort of setup for the flowering aero
chamber?

how about a large propagator hood?

can they be made to fit any size res? i found this insanely sturdy cooler that i am making my flower aero chamber

Ok so for the lid I would use plexi glass covered with a light proof material. If you find that the top bows from the weight then you can add a simple support frame out of pvc. And I don't think the pop up sprinklers will work due to the fact they need like 80 psi min to pop up. But if you look hard lowes or depot will have the tiny sprayers your looking for, sometimes they even have neat little patio kits that have sprayers, tubing, manifolds all sorts of goodies.

Okay thank you minigrows.. i will return the sprinklers then... that was what i was afraid of anyway, that perhaps they required alot of pressure to work. i did find alot of the little misters just none like the red ones that is see everyone using around here. as for the top, i think i am going to ask around at the sign making businesses in my town, that plastic they use is perfect. But then, so is what you suggested.
