Ok.. i can understand your situation and i can understand that after studying all those long years you come to a situation where it's difficult to get a job and it's depressing.

As ppl here suggested rightly... you have 2 options

1) Baby Sitting. i saw many ppl asking for a good baby sitter and who could be better than a mom of 2 kids. this jobs suits you.

2) Delicious home made food. i am sure many indian guys would like it. on a small scale you can start it from home and cater nearby people. i guess that will not be a problem. it's not like a business. you can treat it like everyday you are giving party food to nearby indians and yes profit margin is very high in food business. sometimes it's almost 100% profit. give it a try.

3) Give Ads on Qatar Living. i Guess you will get reply.

i know i am repeating myself as these suggestions are given by other ppl here and i think this is the best way to quick start.
