Design current preamplifier

I need to generate arbitrary waveforms with National Instruments NI 6221. My signal has a very limited bandwidth of less than 100Hz (max current 5mA, max voltage 10V). I need to design a circuit to precisely amplify the current with variable gain (in the range Gmin=10 - Gmax=100).

Does anyone have any suggestions on a simple design to do the job?
Thanks!!

Something based on this, perhaps?

Thanks a lot alec, very much appreciated!
