Ian,
I'm with Rise n Shine on this, you're speaking like a cold call salesman on the phone!!
You're working on the strategy that, "If I can give you something that will make you money would you be interested??"
In theory everybody would say "YES", however in practice most people will not respond because they are waiting for the catch! Which there invariably is..............or maybe I'm just being cynical!!
People don't understand what you are trying to get at, if you want people to show an interest tell them what it is, show them a working demonstration.
If you are confident in your product then it will sell itself, however, if you're all fast hands, shadows and false promises then forget it.
