Hi Richard,
The customer needs a new page and a qListForm on it configured to DisplayListItem and linked to the list. Also he needs to add the desired fields to display.
Then on the page with qListView on it he has to pick a column name, got to Edit, then go to LinkTo field and add the link to the new page created above and append this &ID=<%ID%> (ie .\MyLibrary\MyPage.aspx?ID=<%ID%>)
When the user clicks on the column that now is a link it will open the page created above and the qListForm will display the item.
Other method would be to edit the DisplayView page of the list, hide the OOB list view web part, add a qListForm on it.
Please ask him to check the documentation for more details.
