As @alexvan pointed out, it makes more sense for the DAO to fund something by project rather than by hour. Land is probably not the best fit this.

Instead of this proposal, SPL could ask the DAO for funding for NPE development (or other projects that can be completed over a shorter timeframe), and use their internal funds to complete the land project. If everything goes well, this could amount to the same amount of money anyway, but in a way that makes more sense. This NPE funding proposal should include a clear plan with smaller milestones, which upon completion will unlock payments from the DAO.

This way, the DAO can be much more certain about getting value for their money. The amount asked for here leaves the DAO very short handed, as @clayboyn stated in the discord thread:
