SecondChance used clothes marketplace - Looking for a technical cofounder!

Want to start a B2C marketplace for used clothes. In the beginning this would be in Switzerland.In countries such as Switzerland Denmark etc. there are second hand shops run by RedCross volunteers.In these shops there are usually a good number of clothes in a good/decent condition which are sold at a much reduced price.The problem is that they are not catalogued / online.Often parents (mothers) do not have much time to spend in these shops...
