Hi Flyer,
Helinut is absolutely right. To answer your question you must give us a little more info on what type of Commercial Public Transport, and on what type of aircraft you intend using. I know of one new A.O.C. that was restricted to A to A flights only (Joy Rides) until the CP had more experience. In my view this was ridiculous, how on earth could the CP get more experience if he was restricted? Sometimes a neighbouring CP or your TRE can help give cover.
In answer to your original question there are no minima for a CP under JAR OPs, there used be under CAP 360 it was at least a 1000 hours or even better an ATPLH. Before that I’m sure you had to be an ex Royal Navy Pilot! Now you only need this to be a FOI.
My advice to you is to be able to demonstrate to the powers to be, that you can do the job safely and professionally. If you want any more help please feel free to contact me.
Good luck.
