I'd recommend Budget Blinds. budgetblinds.com
They do custom work as most windows are not standard and even can be off here and there by an inch or two.
(nothing looks worse than getting something cut somewhere else and then have it not properly fit your windows -- or anywhere else for that matter!) ;-)
They have woven woods, which look really good, and offer a LOT more than blinds, such as shutters, roman shades, motorized shades, etc.
They can work with your budget.
They also have some good deals and relationships with major suppliers such as Hunter Douglas.
Remember when you get an estimate, compare apples to apples. A lot of times what Budget Blinds offers is of better quality and features, like warranties. They also come to your home which is convenient as well as you're able to see how something looks.
Big box places SEEM to have better deals, but then you work with middle men installers, etc. Even JCPenney custom's quality isn't as good as Budget Blinds, or their selection.
Good luck!
