We've put together a Just Giving Site for the project- the objective is to raise funds for the materials.
Practical and professional support has rolled in for the project, but we still need a budget for materials. The plan is to use as much that can be found, scrounged and donated as possible, but the thing definitely postively needs to stand up, and for that some decent solid materials will have to be bought. We also need to hire a number of bits of machinery, including a hole borer (otherwise we'll spend 2 weeks just digging out post holes)...
Please please please... give generously to support the project :)
