I am with Les all the way on this, if you bid for a job, you are honour bound to know you have the ability and resources to carry out that work without resorting to asking for help from non company personnel, especially on-line volunteers.
Similarly, those that issue the contract should be sure they give it to those who can fulfill the requirements 'in house', the Coal Authority are not shown in a good light by this thread.
It would be interesting to see the presentation given to the CA in order to win this contract, I wonder if the OP comes within the remit of 'A comprehensive internet search', a term I have often come across and really means 'Its Winter, Its cold, and I can't be a*sed to leave my nice warm office'.
Always remember, nature is in charge, get it wrong and it is you who suffers!.
