Patrick is right below - Franks Lumber on 15th in Shoreline is pretty amazing. I got a beautiful door there and they have some custom beauties - not so sure it is good for windows, but it has been a little while since I have been in there.
I hope this works for you. If you remember, let me know how they treat you and their service. I refer them to many clients, and have used them for my entire house, so it is important to me that they are treating people fairly and giving the same level of service I give my clients. Good luck with your remodel!
