I recently set up a Pozible campaign to raise funds for a solo exhibition I have coming up in April November 2013. Pozible is a crowdfunding platform for creative endeavours. From the Pozible website:
Pozible provides project creators with a platform to present their ideas to a worldwide audience. If anyone likes the idea, they can support it by pledging money to the creator's project. In return for support, the project creators will offer rewards depending on the level of funding; essentially differentiating itself from the normal funding process.
