Not sure that would work tarik:
Lots of professions are paid by the hour with differing fees depending on experience.
As an example I will use a Lawyer. I want a lawyer so go and find one that I can afford with appropriate experience - fine.
Problem is that aviation doesn't work like that - hundreds of people are hiring you simultaneously and the ticket price is fixed - so it is not the customer that has a say in the price they pay for the pilot. That is where the problem occurs - with those whose say it is, ie the beancounters.
They don't care how much experience you have, just that you are legal - they are lots of safeguards to ensure that even a junior FO with a junior Capt don't crash and put passgeners off flying with them. So what they will do is hire an entire fleet of 250 hour FOs and 1500 hour Capts. If you are working with the company and you accrue too many hours (and become too expensive) they cease to use you - effectively sacking you for gaining too much experience.
