Try ringing round the large supermarkets they now like the local supplier why not the local small buisness trolly stands oil spills ect, take a look at there stores first see what needs cleaning .I sent 73 buisness letters out have had two replys one has got me two jobs ,one for the virgin group and the other one has invited me to a breakfast meeting with about 80 other buisness people have to stand up and sell what you do they in turn sell for you (networkin) not lookin forward to that but it has to be done .
It is tough out there but you have got to hang in there and do what it takes to keep going.
