How to find a Turkish lawyer for a prenup agreement?

My fiancé and I are getting married in a few months and I would like to have her sign a prenup. I hope that my marriage lasts forever, but I want to be prepared if it doesn’t. Do I have to disclose all of my assets before we sign the agreement? I don’t really want to tell her how much I have. Also, I would like to hire a Turkish lawyer, can that one lawyer represent both my fiancé and me. My fiancé will trust whatever lawyer I pick and I’d like to avoid excessive legal fees if possible.
