If you need a quantity, you want to find a bulk soil product rather than bagged - bagged soils will run you at least 3-4 times the price regardless of quality. And you probably do not need all compost - a planting mix or some combo of soil with added organic matter is better than 100% compost for raised beds. Don't let folks make you feel guilty about buying soil or compost. Not everyone has the luxury of time or space or ingredients or ability (or even community permission) to make their own compost or in the quantities required. And you cannot "make" soil so if you need to fill a bunch of raised beds, importing soil is the only reasonable alternative. Folks in very urban areas do it all the time and it is becoming more and more common in suburban locations, especially those with small lot sizes and crummy native soils. Check this place out - they are throughout CA and look to have a decent product. They deliver themselves but only on large orders but they also supply various retail outlets. Call and see who might be available close to you. If THEY don't deliver, rent a pickup from uHaul or wherever or borrow a friend's.......it will still come out cheaper than buying umpteen bags. The Premium Planter Mix is what I'd go with............or you can do a part load of that and a part load of the compost. Check the analyses first :-) Here is a link that might be useful: SoCal bulk soil supplier
