You pay for your endo, with no guarantee of a job (basic protection if you are a muppet). You then do co-pilot runs to the mine, which is paid btw, until you have sufficient ICUS hours. You need around 700h total time to do the Island flights, so if you have less its a hard slog to get the time.
Once you get the requirements you do island flights until you can do mining runs, but chances are you'd prob move on to that point.
TL
R good company, get paid for ICUS (ie income), slow progression and you need around 9k lying around if you want to get endo and ASEPTA training.
