Mosfet Amplifier Problem
I will advice you to use 2 stages.

First stage should be CS amplifier and the output will be the input for a CD amplifier which will operate like a buffer.

So, the first stage will give you very high gain(maybe if you design with active loads and properly values for W/L) and then the CD has the ability to give you the same gain(usually a little smaller) for every load you connect.
