Failed business strategy #1

Today and yesterday there has been a white van parked outside work. On it is the name of the company (Grasshoppers), two phone numbers, an email address and the suggestion "Why not give us a try?"

Now, the very obvious answer to that is Because we don't know what the bloody hell it is you do. Unless they supply grasshoppers, of course.

Surely this is such a fundamental thing that no one bright enough to run a business could miss it ?

Another one for the ????

( Another of those dialect-word questions )

And I think I need a new phrase inventing: what do you call a bunch of people (that's you lot :) to whom you can pose questions, and whose collective brain you can trawl for information ? Something of the search engine, something of the test audience, something of the lab rat. Any ideas ?
