Hi Night Star,
Welcome to Hobby. 
I am keeping pigeons for over 20 years. I don't agree that "Yeh tumahin tabah ker dain ***". I am software Engineer and doing great job.So don't think like that.
For business, I would like to ask a question. How do you rate your PR ? Do you have friends or know some club that you can join to enhance your relation with in hobby mates?
It is good business and I know few persons who not only sell local breed but import and sell in local market. You just have to have good PR that people know you and consult you for buying.
For breed I would suggest to go with fancy birds. like pouter, frill back, croper etc. Because you can't sell homing pigeons or tipplers if you don't have good results in it. People like to keep birds for kids and they look good, You can sell to that target market.
One other thought is to breed parrots. I would not suggest to have expensive one but cocktails. Like with your first point, people don't like pigeons due to abc reasons, but even those people like parrots. cocktails are not expensive so in range of many people. you can breed them and sell them via online listing sites.
Thanks
