There is lots of free, or nearly free soil base's for your raised beds. Most town's/cities have a compost site where you can go get lawn debris,that has been composted for the bottom 1/3-1/2 of your raised beds. If you live in a rural area, straw, leaves, grass clippings, wood chips, and sawdust are often readily available. Top that off with a commercial top soil potting mix and you should be good to go.
As for keeping the critters out, human hair in an old nylon stocking placed around the garden works great.
