I just visited a friend while we were in our old town for a medical appointment and I never even thought to ask and I have been offered a truck load of old manure. WOW!!! I am tickled pink as our "soil" is mostly sand. Looking in the back yard you can tell there is no nutrition as you can hardly find a blade of grass and even the weeds are small. Another friend with a small sheep farm has already offered a load of 3 - 4 year old sheep manure so with the two lots I think I should be all set. I had already framed in one of the beds and started to fill it with seaweed, old leaves, etc., but realized it would be very slow to build each bed that way.
