It is quite true that a Form 1 can be generated for the cost of the toner & paper......................... Oh and you have to be EASA 145 approved so you need Licenced staff, pay the EASA approval fees, have buildings, offices and a stores system that meets EASA approval.
So to support that little lot you need to be charging about £55/hour for your Labour.
A bit more than a bit of toner I think !
