Limited funds are no obstacle to starting your own business from home. Many fortunes have been made by people who started out with no money.
You start by knowing your talents, abilities, interests. To be successful, it must be something you like, because you will be spending a lot of time doing it. Then you need to assess your resources. Money is a small part of this. Your resources could be your computer, your kitchen, your basement, whatever you have that you can devote to your business.
There are a thousand things you can do at home to make money. Host sales or gold buying parties, trim hair and do perms, cook food for business lunches for a local company or their employees. Host private dinners at your house. Raise mushrooms in the basement.
Find a business start up checklist or two from government agencies or nonprofits and this will give you more ideas about how to organize your business.
