Attic Fan, Whole House Fan, Pressurizing Attic?

So I'm looking to create a kind of distributed Whole House Fan. There are a few Rooms in the house that I want to Vent, so instead of venting the entire house into the Attic, I was going to just do the 3 rooms I wanted to vent and have the ability to vent them one at a time.

So I've been looking for a Small Gable Fan that I can hook up to a 15" Duct and a 15" Square to Round Can in the Ceiling. Then vent the Room Directly into the Attic. Thus causing the hot attic Air to be pushed out the Existing attic vents (eyebrows, soffet vets, etc)

The NuTone N-GF900N was the unit I was looking at as it is a 900CFM unit. Though that seems to be discontinued and the only one I can find now is a

1140CFM unit, which is for 1630 sq. ft.

I want to stay away from the larger units as I don't want to Pressurize the Attic. The vents int he Attic are only rated for so much flow and If I have too much flow in the attic out the vents It will start to come in the Light Fixtures, etc back into the house.

So Is there another Fan besides the NuTone N-GF900N that is 900CFM or smaller? I cant seem to find one. Is there another fan out there that I could use that is around $60-$80?

Thanks!

There are several whole house fans out there that are 24"x24" and there are a few that are the Dual Fans that fit in a typical Attic Stud bay.

I'm trying to do something like this:

It wont be attached to the Ceiling, so you wont get the noise and Vibration.

90% of the time I just want to cool the Bedroom at night. So that's where I wanted to start.

Thanks
