Canon remote release / Nauticam

Does anyone have a remote release that I could fit to myCanon EOS 1Dx/ Nauticam housing?

Doesn't need it to be too long, just want to be able to do 'B' bulb exposures longer than 30 secs.

If you have something and are willing to sell or hire it to me, give me a shout. I need it by April 10 and can return it after 20 April.

Thanks!

Hi Alex, I ordered one on Sunday and it was shipped today, should have it by the 9th. Thanks again!

Did it work out? Did you acheve with it what you wanted. I am looking for something similar for my camera.
