Feel for you mate. There is work out there it's just a matter of finding it and perhaps more importantly believing you can find it. Whatever you do don't try throwing money at it as the returns on advertising are likely to be poor if things are that quiet and that could just make your financial position even worse. Best to do things that cost nothing, emails, leaflets, door knocking, mail shots to past customers, making contact with lettings agents, contract cleaning companies, tele sales calls to prospects etc.
stick with it.
