Well, before you have a CPL license, you need to pass the SPL. There are numerous institutions worldwide. Philippines being the most economical. But, a CPL license holder from Philippines are banned to fly for most Indian and renowned carriers worldwide.
India too has a few academies, but if you enroll in them, make sure they have night landing and handling facilities. Advantages of doing it from US or Canada is, they have their own ATC to guide you. Although, they do make a hole in your pocket but never mind. Once you clear the medical tests and get their enrollment form, banks will start approaching you for loans. These are long term loans.
Once you get into an airline, you start as a trainee pilot and have to clear their standard according to the equipment you fly and endorsed in. A Boeing 737 NR or an Airbus 310 or 330 is advisable then you rank up as a First Officer. Well, as a F/O your salary ranges between INR 80k to 1.30L depending upon your merit in negotiations and flying records.
Well to answer your second part about difficulties. Do you think cooking an omelet is easy? No, you make it easy by the way you learn the smart or hard work. Hence, if you take training seriously, it's a cake walk.
