Go back to my first posting above. Go on a symbol mining expedition using the links I posted. I would start with the Dundjinni forums. There is a huge selection of pit objects on the various forums. RPG Map Share and Greytale's Nook also are good sources.
Most people who offer objects on these sites allow free private and commercial use, but redistribution of the objects themselves is not allowed. For that reason, you'll have to do your own mining.
