Mike don't get so down about it, they say if you do nothing expect nothing.
You've got a computer get some letters printed out and send them to old customers, then send some to pubs and nursing homes and childrens plays centres and nurseries. Get leafleting if you do all of this the phone will ring and you will feel better and the phone will then ring some more and recommendations will come in. Consistancy is the only way you'll get work and keep work coming in.
