Kimberely mentioned a couple of things on the topic of my market idea one interesting thought was the implementation of micro finance schemes.
micro-finance has evolved as a need-based policy and programme to cater to the so far neglected target groups (women, poor, rural, deprived, etc.). Its evolution is based on the concern of all developing countries for empowerment of the poor and the alleviation of poverty. Development organisations and policy makers have included access to credit for poor people as a major aspect of many poverty alleviation programmes.
