A network of small and large partners to support all projects of the exposition; and multiple modes of financing, including the involvement of citizens through the "crowdfounding."
and there is this:
Projects – Regarding the crowdfounding will be activated in the coming months platforms needed to start collections around specific projects that will be identified or who can report to the Committee. The proposed contribution will all be received and considered by the Organising Committee, which will use a ‘grid’ of ethical criteria that help to assess the compatibility of the proposals with the objectives and style of the exposition.
Companies and individuals who are interested in collaborating in the preparation of the exposition can take right now a first contact by sending an e-mail message to this address: firstname.lastname@example.org .
Crowdfunding has been discussed in relationship to the shroud and even tried in one instance by David Rolfe. See Crowdfund my meth lab, yo and The Shroud Affair Crowd Funding Campaign: A Guest Posting by David Rolfe.
Maybe it will work well.
