I don't know about funding, but variety is crucial to a good course. Varying distances, curves, ceilings, tight and open shots, etc. are all important for getting a complete disc golf experience. I've played many courses that have done a great job with this; it seems to be those that don't that i don't find myself going back to.
Don't cross fairways (especially from short tees). Really I have yet to see a course that has done this and actually needed to or that one of those two holes was the most awesome on the course. Leads to huge backups and is confusing as hell for anyone who doesn't know the course.
My pet peeve.
Keep in mind that when you propose a course to a park director, etc... what they are looking for from you. Come prepared to answer the questions that you know they will ask. Costs, Land, maintence. Don't be shy to ask for money. Go for the gusto up front. Get an idea of the amount of funds they can commit. Tailor your proposal to each individual. The hardest thing for me is to remember the beginer and the unbelivable places they can make a disc go. and so much more
