We have need for means to manage logo's of our contributors. Each year we participate in a non-profit event for the citizens of our town. Over 150 contributors help us by giving money or materials. Managing their logo's for display on website and indoor advertising (which logo's do we have, and in what quality) is a tedious job. We have a functional design of a web-based (joomla) system but we need someone to build this for us.
