156123 PDG Commerce integration

I have an existing web site written in htlm and asp, and want to integrate PDG Commerce with it, including setting up permissions, etc. probably adding/modifying features once we have an idea how it works. The files have already been installed on the server, but they don't work for some reason (I suspect permission file/server problems). Any idea how long/how much the integration would run. The potential feature changes will be needed at a later date if at all. Thanks,
