Here's my suggestion
1. Go work for them for free
2. Document all the work you do including hours onsite
3. When ready to quit take em to court for unpaid wages
This will show that you are:
(a) An idiot
(b) A scab who cannot keep his word
And the dodgy organisation that employs you will get lumped with a bill that may well send them to the wall.
All problems solved.
