Anyone have any thoughts on good sourcing or what I should be paying for custom made sashes? I need an upper and lower double hung. It is bowed. Each sash is about 51 inches wide and 32 inches high.

I also need an eyebrow window sash and a round sash (33″ across).

Any toughts on what I should be paying for these and sources would be greatly appreciated.

I’m in the Boston area, if that helps.
