Well, you can get temorary pleated paper at home depot for 6$ each for now, and get what you want later. I did my house on a tight budget and have white wood blinds (2") in the main areas and PVC cheapos from home depot in the bedrooms and kitchen. I think the wood for 4 windows cost me a bit under 300$ and the rest cost me less than $25 each
I ordered from
www.blindsgalore.com and was pleased, there are many others though. I don't know how much the duettes run, that sounds like what you're looking for. go price them for yourself.
