Hi I want to start new business without capital or minimum capital in small city karad or satara in maharashtra

Most businesses will require some sort of capital to start-up and operate.

You need to know what skills, services, or goods that you can provide that people will want.

For example you are good at making deserts, you could open a bakery.

India is noted around the world for fine cotton and silk textiles and also for embroidery with small mirrors on cloth, among other things. I would start with light cottons, maybe some silk saris for all the Indian women who are living in other countries.
Buy a few near you to start and sell them online, alibaba.com or eBay.in. You will need to know international postal costs and rules, and you will need an online way to be paid.
There will be competition no matter what you choose, so it will be hard work.
