Hi Admyr, welcome.

First we would like to find out a little more about what you would like to do with the craft.
Do you want to get molds because you want to make a large quantity of religious statues? If you just want to paint your own statues then you don't need molds, you can buy these statues pre-made from a good store such as Statuary Place, or someplace close to you in Arizona. Or you can mail order them from Statuary Place.
If you want to pour your own molds, then this requires more materials and learning some new skills. Do you want to create plaster or ceramic statues? Plaster statues are easier to make but break easier. Ceramic statues can have fine detail and are tougher, but you have to use a high-temperature kiln to "fire" the ceramic to make it solid. So ceramic is more complicated than plastercraft.
