Yes. You will be pleased to know that one of the programs is the InBusiness Initiative that seeks to develop persons with disabilities with business skills to run their businesses effectively as well as linking them to markets for their products. The InBusiness Initiative is an initiative of Light for the World.
The National Council for Persons with Disabilities also has a grants programme to buy productivity tools for persons with disabilities who want to start a business. That is, if for instance a new sewing machine will boost your business as person with disability, the Council will help you by buying the sewing machine for you.
