Rostering, hotels is the least of your worries, the problem is getting on line and the endless paperwork and delays it takes to get you there. Plan 8-12 months if everything goes to plan and even then that is with 2 med and 2 sim rides passed, plus the atp exam which is not a walk over.
The money is there for a reason because its hard to get over the line and they have a high need of capts but due to their rules (one of which is ruling many nationalities out of applying due to the diplomatic relations rule) most people can not , its not there because the air is bad, the chinese are difficult blah blah....
