Can you get children's play sand where you are? If you can that's fine to use for hams although you do need to dry it out in the oven before using it.
Sorry to hear it's so hard for you to find appropriate things for your ham but finding things like a suitable substrate of some kind is really important. Can you get hemp there?
What country are you in? You may be able to order from some web sites that ship internationally.
