So, are you having the soil delivered and just dumped in the space where you want the raised bed, and building your border after the company dumps the soil? You could always spread any "extra" soil around as fill or find a place out of the way (perhaps behind a shed etc.) to dump the leftover. It's been awhile since we had topsoil, red sand, mulch delivered for us to play with
but if I'm remembering correctly, your 7 yards of topsoil is probably going to be at least 5 or 6 large wheelbarrows full!
