If you have a scrap metal yard near you then you are made. Redimensioning stock is one of the basic skills you will need to master so initially I would find some mild steel and forge up some fire pokers, rakes and shovels. Remember to work it hot (yellow) and keep it hot.
As for hardies, etc old springs are good for these. Bit different to handle to the mild steel. Don't heat is as much, up to bright red, and definitely don't beat it when it is cold as you could crack it. When working this metal the anvil can actually have a hardening effect on it as it cools the metal quickly, a bit like a quench. If you keep beating it then it can crack easily.
Above all else, have fun and learn :)
