£45-£50 per FLIGHT hour. Maybe get a little bit for groundschool/briefings, but unlikely.
You might get a small monthly retainer (£200 per month?), but for that you will probably have to be there 8am-6pm everyday, regardless of if you are flying or not, to wash helicopters/answer phones/do paperwork/drum up business/push aircraft around/insert detail of exploitative task here.
