HI,
It seems u r new to everything.
The cost would range from 35,000 to 50,000 US $ depending on what all u want to do, whether u want to do any specefic type rating or not.
A CPL with 250 hrs might not fetch u a decent job...may be even job less..
Definitely going into the Air Force is the best option if uwant to save money.
Dont know the situation in US. In india lot of ex-airforce work with airlines.
In India u need to have physics+chem+maths in ur 11 and 12 yrs of schooling...think US dont require that.
Hope u got the answers 4 what u asked.
Do ask ur doubts..
Regards
Kanak
