Perhaps you have heard of LETS, timebanks, or other community projects in which arbitrary currencies are created? Well, there is now a suite of modules to support communities trading in local money?
Currently the suite consists of three modules, a directory of members' offers and wants, an optional autocategorisation module, to help with consistent use of categories, and a transaction module. Later it will be possible to define multiple currencies, do taxation, and much more?
Some organisations I meet have a clear idea of the web sites they want, or think they do. They will write an RFP (Request For Proposal) which broadly outlines all the features of their desired web site and I think they expect that someone will walk in and build it as described. Using a modular system like Drupal it's very easy to allocate each feature to a module, and implement several features per day until the job is done.
I live and work in Geneva, the NGO capital of the world. Just in order to pay their overheads, organisations here need solid core funding. Switzerland must also have one of the highest costs of employing staff in the world. This usually means that when an NGO wants a funky web site, they can often afford to pay a commercial developer up to $1000 per person-day to build it.
