i subbed from haytn coulthard years ago and left just before they got reamed for opertaing offences,and they paid 90 days because they were miserable tight assed d&g choochter gits,though they could afford to let the golden child play with his racing cars.
you eventually got paid to the exact penny but the difference for the o/p is they wernt in any financial difficulty and were just miserable,so in your case,id shy well clear.
quite often the quicker your paid,the poorer the rates.
might not be so bad if you are using their fuel card though?
