How hard is embroidery?

How hard is it to embroider...I do not have much experience with sewing machine. Mainly all I wanting to do is embroider cute graphics and customs names on baby items for a business i currently have running. I have tons of customers wanti8bng these products and I need to know how hard embroidery is. The machibne I have looked at is the singer futura because it appeaqrs to embroider for you once you put it in the computer. is this how all embroider machines work. What is the best one to use...as i said i am new to this and want something that will be easy to use and I love the idea of hands free bevause the though of sewibng a difficult design is kinda scary to me
