I Guess you are in the USA (Pittsburg),  So NRC regulations apply
10CFR30.71 Schedule B gives exempt quantities (licence free)  for
various byproduct materials. The exempt limit for Cobalt 60 is 1uCi, for
Cesium 137 it's 10uCi.
You cannot there fore obtain 1mCi of either without a licence. 
I do not know of any general licences that might be applicable.
You could of course purchase 100 10uCi Cs137 test disks.
Spectrum Techniques are a good supplier, see <

Can a 1 millicurie source of Co-60 or Cs-137 be purchased without a 
license? If so, can anyone suggest a vendor?
