Thats what I thought. The rate you showed of £600/350 for a Hawker seems awfully high to me. I would expect to pay £350/200 plus about £90 per diems tax free but I would pay for an OPC plus a LPC if necesssary and any ground subjects (CRM DG's etc). The pay would include any days off down the route.
Not employed frelancers for a long while but might so so soon, so this info good to know
