I think your heart is in the right place too Gav - but I'm afraid your business sense isn't. All that really matters to most individuals/organisations/businesses/governme

and the like - is making money! The African factories have closed because too many people in the business world and governments of Africa and China are making too much money for themselves. Those are the individuals with the economic and political power and it is those individuals who are only looking after themselves. They don't care about the little man or woman living in poverty in some rural village. Those people have no say - money does!
It's much the same with the designer names and labels you mention. The only reason designers, celebrities, manufacturers, agents, promoters, retailers etc get involved in a product or celebrity name - is to make money! If they were feeling charitable it's a lot easier to just write a cheque and take the credit without possibly compromising the name or reputation of a quality product or celebrity by linking it with poor parts of the world. It's also dangerous as those areas of the world are often subject to rule by unsavoury characters such as various terrorists and mass killers who find themselves flavour of the month or hunted criminals depending on the arrows of fortune (evidence Gaddafi, Mandela, Mugabe, Amin etc etc. ) Who would attach their wealth and reputation to that bunch? Imagine some designer recruiting Winnie Mandela - then learning about her so-called Soweto Football Club and their murder of Stompe?
There's also the issue that most of the money earmarked for charity doesn't get to the people who need it. It was known a few years ago that only 2p of every £1 given to Oxfam actually got through to those it was donated for - 98p went in administration and salaries! Hopefully it's changed now - but I used to visit Oxfam HQ in Summertown as a chauffeur a few years ago and I was amazed at the scale and obvious cost of what was happening just there! They weren't all volunteers either - many of the people I met were on good salaries!
It's also recognised that a lot of aid is used by regional governments or warlords as a weapon or for political purposes - election bribes for example. There's nowhere more corrupt than Africa and much of the aid sent there lines the pockets of those oppressing the very people it's supposed to help.
Only when those issues - Oxfam's internal adminstration costs/salaries and the widespread corruption at various destinations - will people be more inclined to hand over their own money. Of course, many of those people are only concerned about paying their own bills or increasing their own finances anyway, not in giving money away.
Good luck with your idea and I hope it works, but many people don't like those issues I've mentioned here.
