keep trying your local nursery's some one will possibly have
some left in stock, or put an ad in your local paper for stuff
you require and ask if anybody has any to spare
try making animals and then if you get good enough you can
sell you will need a strong mix of sand and cement, i think you
can buy frost inhibitor to put in your mix i would think you should
try 3 to 1 mix and see if you think it is strong enough
