Moth Ate My Sweater!

Pls help.
My favorite cashmere sweater has a huge hole from moths. Where can I get
this repaired that is also inexpensive? I was hoping if someone knows of a
place in Chinatown (NYC) that would be able to do such repairs. I know my
local dry cleaners do it, but it's so expensive.
The sweater is vintage. The cashmere is light, supersoft and the yarn is
fairly thick.
Thanks,
