Can't find dark blonde curly hair!

Hi everyone! I'm so frustrated that I can't find dark blonde curly hair wefts. I'd like hand tied, but I'll settle for machine. In many brands, I'm a color 18. I'd like 16 to 18 inches.

Bohyme's 18 is too dark for me, and I can't find any other suitable colors in stock anywhere - all their blondes are too light (their 16 is like a child's doll bright yellow!)

I need a deep wave - anythign called 'body wave' generally goes pin straight after the first wash.

Any help most GRATEFULLY received!

Thank you!

I used to have beautiful natural curls.  People would stop me all the time and ask about it.  I have been getting it highlighted for years at a beauty school.  Every time I go, I have them blow it out straight.
