Portable Projecton theater Project

I have been tasked to provide equipment for a portable projection setup where the client wants to play movies outdoors and even use the equipment inside if they wanted to. Right now we are in the planning stage and have not yet put together this system, but here are my thoughts.
First of all i want it to be as self contained as possible, then less parts the easier it is to store and use. I have found a enclosed case that will contain the amplifier, DVD player, and projector. This case has wheels and a collapsible handle so it is easily transported. I will install Speakon quick connect speaker terminals on the side so the users will not have to mess with connecting speaker wires to the amp and they can just plug in a premade 30′ cable from the box to the speakers. There should be enough room in the case to contain all of the wires when not in use.
The screen I plan to use is a Fast Fold Screen by Da-lite which comes in a carry case and is fairly easy and quick to put together. The Da-Lite screen can range in size, but i think a 12′ diagonal screen should be good for any viewing area.
So the parts to store would be the screen, the case and the speakers with or without stands.
I would love to know if there is a market for this setup in a residential capacity.
I will post pictures of this setup if it comes together.
