You can collect any workschedule under dcam 145 companies.
For your case is 5 years. The first task until the last should have 5 years min duration.
After all done, get your CAA license.
Than do conversion by mod9 and mod 10. Get DCAM. (For now, we donno what will happen in 5 years time)
Than type and company, than can sign 9M.
By the way, since you got 5 years to go right, take DCAM papers as well, easy collect 1 workschedule can apply both parties, no need do conversion.
