Post em Savar Upazila, Dhaka Division, Bangladesh

There are many interesting characters you can try - depending on what interests you. My suggestion is to mix things up - like a nurse who is also a single mum, a house-keeper/mum, a bus driver/father of threes or a rickshaw driver who at time of harvesting goes back to his village and becomes a farmer etc. I can hook you up with my housekeeper who works in my apartment. She is too old to do heavy work. I employ her since I don't have much to get done at my place. She comes to my place every morning, feeds my dog, waters my plants etc and goes home. That's how she supports herself and her daughter who is studying. They live in one room together in a slum area. There are many stories like this. You can also get creative - like make a story of a hijra(transgender) who begs on the street or the escort girls in dauladia etc. Bangladesh is full of stories.
Best of Luck.

I can take you some places where you might get more similar stories as you are looking for.
