Designer - corporate ID

I'm looking for a designer to develop a corporate ID for my start up social business, initially this will just be a logo (for now) and a full brief will be given in advance.

Brief -

Thrive for Good -

Online and traditional marketing practice for charities and not for profits. The logo will need be very contemporary to reflect the idea of charities moving into the online engagement arena, quirky but professional.
