icons for each program

i am working of a process map for developing a large program with articulate.  I will have three or four others working on the process and would like to clearly label the planning map as to what has to be developed for each part, i.e. what we are doing in an egange, what will be in quizzmaker, what will be a pdf attachment.

Does anyone have an icon set of all the articulate file icons, or should i just do a snag it of them
