Import Feature Classes

Hi,
I am trying to create a model whereby a new file geodatabase is created (done that bit) and all feature classes from another file geodatabase are loaded into the newly created file geodatabase (I cannot simply copy the geodatabase it has to be a new geodatabase then add the feature classes). Once the feature classes are in I need to delete three fields from each feature class.

I have tried using iterate - feature classes, adding the existing geodatabase then using the feature class to feature class tool to export to the new geodatabase but it only lets me do one feature class at a time.

regarding the delete fields I added the delete field tool and specified the fields to delete but I am unsure how to iterate through the feature classes as the option to iterate is greyed out.

Any help - most appreciated,
thanks
Mark
