you are allowed to work in US(being an Indian) as a CFI for half the time training recieved at the flying school so if you undergo flying training for an year you can be employed by the school for six months on M1 Visa.
As for Dean International its a pretty good school with some problems that are their in all the flying schools in US training International students. But advantage at Dean is that it has a desi touch to it, run by a desi, dispatcher is desi, accomodation provided by desi and even some instructors are desi's. As far as training is concerned its your instructor who matters if you have a good instructor you should be in no problem and yes if you pay in advance then you cannot leave if you are not satisfied or the school goes bankrupt.
and yes with a lot of pilots in india and a lot more by the time you finish its going to be tough to get a job for all of us even if you have 500 or 700 TT airlines would ask for a type rating and might even ask for a college degree which is norm in US.
In the end dont get discouraged by the competition because there is always a Job for the BEST!!
Best Of Luck
