I'm fairly new to casting (not an expert). You might want to consider sand casting. I have made sand castings of flat backed items that I made out of clay and they turned out well.
I learned how to do this from "Practical Casting" by Tim McCreight. The instructions in this book are straightforward.
The metals I've used for casting are bronze & brass. I think these would hold up outside - other people on this site could provide better info on this. I hope this is of some help to you.
