Your first problem is that a 741 amp can not function with the input at zero and the negative power supply at zero. Think of it as head room, or in this case, foot room. You need to supply the amp with a negative supply voltage so it can get to zero on its output. Either that or use a different amp chip. Second, the inverting configuration inverts polarity, not the range of voltages. To get a range inversion, you need to pump in a current to force the range to change. For this, we need to know the impedance of the supply voltage, so we don't mess up your incoming signal, and, "how accurate do you need this?" The current injector will need to know how accurate to be.
