Help writing wanted ad
 

I am trying to write a wanted ad in Japanese.
This is what I want it to say;

WANTED
Karatedo Instructor/Sensei
Inquire within

Here is what I have so far;

望まれる

空手道
先生

Please complete this for me.
I am open to all suggestions, corrections or criticisms.

求む
空手道講師
中でお尋ね下さい

We don't use the word 先生 in this case. It's how a student addresses the teacher, but it isn't the name of the profession.

So what's the exact phrasing of that in English ?
