I am looking for a company that will sell or manufacture to sell fake,
practical joke style toy dog poo.  An example is the first two items
on this page: http://www.sillyjokes.co.uk/p-jokes/fake/poo/index.html

The order would be approximately 100, with regular monthly orders of
the same or more.  Supplier may be UK or international.  The unit
price must be less than 60 pence Sterling (that includes shipping). 
Full contact details of the supplier required.
