Understand your desperation and am sorry for that what happened.
No, unfortunately I don't know anyone who could take such an action.
Please mind it is very very hard and risky (as this is illegal in the most of locations) to hack a series of systems.

However you may wish to notify the domain register operator http://www.enom.com
abuse@enom.com
and try to ask them for details of the domain registrant.

You may also wish to notify the investigative authorities.

FBI was able to seize bitcoins from silkroad so may the are in power to seize them form coincubess and give it back to you.
Well, I do not believe. Scamers learnt from this story. It's why you have already a chain of transfers.

Anyway it could make their life a bit harder if you report a cybercrime, so there's no reason not to do that.

They may close the site at least.

EDIT:
