The preformed styrofoam non removable forms are worth a look too but if cost is an issue I don't imagine they will work for you. I think they are pretty expensive.

The wood foundation may be fine too if your site is very dry.

We had a builder doing wood foundations here about fifteen years ago and they are a big ding on value now as a used home. They were cheap to buy back when new too though. They are pretty energy effecient too as it is easy to just put batts in the cavities between the 2 x 8 wolmanized studs. Keeping them dry is the main issue here.

Your site sounds lovely.
