Just bought new home, need advice on screen mount

[perfectdark]

Hi guys

I just moved into a new resell home.
The basement is compeltely finished with a drop ceiling (which is nice)
What i want to do is mount my 50" Plasma TV on the wall, run wires behind the wall to ceiling, then over and back down inside wall to my entertainment cabinet. Then i want my projector (120" Electric screen) to be mounted and the screen to come down in front of ym 50"? plasma.
thats my plan

The question i have is... what is the best way to mount ym projector screen? In the past i have just mounted it directly on the wall. But in this case i cannot because i want the screen to come down in front of the 50" Plasma TV. So the projector screen needs to be a few inches away from the back wall in order for the screen to drop down in front of the TV.
I was thinking of hiding the projector casing up inside the ceiling, but this would mean i need to start cutting the drop ceiling frame, which i dont want to do. My only other though was to mount the prokector screen snig to the drop ceiling, but how? With wall hooks (like planter hooks) and have a chain to hang the screen? Was thinking of this as the best solution, but would need a nice looking chain and hooks

any other ideas out there?

cheers
