Convert .ai to .cdr

Hi all

I am professional graphic designer, just need some help in converting .ai files into .cdr. Currently i am working as a freelancer and use adobe illustrator for all my graphic designing, Some of mu customer need .cdr files as they think that coreldraw is easier than adobe illustrator, So what format shall i use for converting .ai into .cdr. I usually prefer .wmf file but some of the layers get disturb by converting.

I want someone can help me in this matter

There may be a plugin available for Illustrator that allows you to "Save As" or export your data as .cdr files. Anyway, a simple google search returns a number of helpful links on doing this.
