Perhaps your first stop should be at one of the import stores to see some in person.
A place such as Cost Plus should have some.
For privacy at night you can clip a piece of blockout fabric over the rolled down shade. Or have a day/night roller shade system.
I have shades that I can see out of in the day but people can't see inside. Of course at night if I have the lights on people can see inside. But as I am typically boondocking where no one is camping or walking closeby so I really do not worry about putting up the privacy fabric. But I do have them for when I might want it such as camping with friends or spending the night in a campground.
If you have the budget a custom window covering company will make your dreams come true and even install it.
