Chocolatier: a maker or seller of chocolate. The chocolatier makes the interesting shapes and designs, with different colours and, possibly, a mix of colours and types of chocolate.

A chocolatier can buy chocolate in a solid brick through a chocolate wholesaler. The chocolatier would then melt the chocolate so that it could be mixed with other ingredients like nuts, peanut butter, or anything that might create an interesting taste, pour it into design forms to develop different shapes and designs for you.
