How much should I ask for stitching charges?

I have a lot of unstitched suits I got on my wedding from relatives, inlaws, etc.. a few of them were stitched by my aunt in Canada but I would rather have them stitched by you when you're in NY (Im in CT) rather than bugging my poor aunt. She's awesome at it though. We have one tailor here who I know of and she charges THIRTY for a blouse, can you believe it? She does a good job though but that's just too expensive. For stitching sarees, I have paid alot in NY at Karishma where I buy them from.. they do a great job.. but again, they are really overpriced.
