Get you some windows from deerview windows and build your own. They make a very nice product.
I'm very happy with their windows. They would be easy to install vertically.
I have bought multiple sets of their windows. Their customer service is great as well.. Last year they shipped a set that was broken during delivery. I was headed to Dallas a few weeks later for the AL vs Mich St. game and asked if they could swap them out. They were going to be closed but offered to leave me the replacement set outside their shop. No questions asked.. I left the broken windows there but it was never terms of the exchange. Very pleased with their product and service.
