I need a group contact for my hacker.  A group where he can trade hacked programs.  The Warehouse 24 group in Runners Companion looks like what I want.   What would be the specifics on that group or can I make them up?

You want or your GM makes you to get a group contact for trading hacked programs?
If its just for trading programs you dont need them as a contact. Same as with magical groups for initiation. (RC,p.126 - When a group is not a group)

Else take it as a normal contact, and adjust its connection rating with the members, influence, matrix resources. Pay for all of it and make your GM agree.
