Standing rigging for an old Catalina 27

Hello,
I have a 1978 Catalina 27 and I think it may have the original rigging. If not, it is still pretty old. I am interested in getting it replaced but have no idea what the cost might be. I am a begining sailor and do not need anything too specialized. Can someone give me a ballpark figure on what it might cost to have a new "middle of the road" rig installed? Thanks.
