That could be the Quoizel Voyager!

do you think the quoizel voyager would be an appropriate fit for a living room with 30 foot cathedral ceilings? We are building and I need a chandelier. Do you think this would be too small?

The Voyager's largest size is the 3-tier 24-light style. Its dimensions are 52" in height, 48" in width and 48" in depth, so a room with such tall ceilings should be well-suited to a light like this!

would 1 chandelier work or would I need 2. just don't want it to look lost

That does depend--if your living room is also very wide/long in addition to tall, you might want to consider two. But if you are aiming for just one statement light in the middle of the room, this Voyager should fit the bill. They tend to come with lots of chain, so you can use more of that chain to hang it low enough that it doesn't get lost in the cathedral ceiling.
