I highly recommend this complete kit from metal clay Ltd.  It contains everything you need apart from the 2 part moulding compound which you can also buy from them.

This is the bare minimum of materials you will need, you will also see some other tools used in my videos which are optional and just make life a little easier.  Don't feel that you need to buy absolutely everything all at once, I have many tools that I use for various things but I have gathered them in my tool box over a number of years!
