Juli, a truly elevated garden sounds like just the thing for you. Gardener's Supply has several types, but they're not cheap. If you have some handy person around you could probably have it built it a lot cheaper. (Sounds like a good project for Ric and Robyn)....
See some of these for ideas. They have excellent user reviews
