Simplest implementation:

Draw up RFPs. These must be significant enough that visible and substantial progress is made on OSE work - but they must be small enough that they are clearly defined.

Crowd RFPs - by breaking these into the smallest tasks possible, these become shareable as social media discussions and requests. See Chunkworks

Bidders review RFPs and submit Bids. Process for this needs to be defined - essentially - specific Requirements that bidders are willing to meet, and proof of qualifications.
Post these at opensourceecology.org, and post funding details on wiki for quick edit.
Donations are logged into a graph of funding as soon as donations come in - through a form that the funders themselves fill out, and that we will manage via a spreadsheet.
The main concept is to show a clear graph of funding progress,
