Old Fashioned Direct Mail Letter

We need an expert. Someone we can rely on to help us get max return on our advertising spend. We install air source heat pumps in Scotland and need a steady supply of new potential clients. (You only install these once) We tried Google. A shed load of money later only one sale. Facebook. Not so much spent but same experience. We tried buying internet leads at £40 a time from online lead generation companies. Should have taken the money and gone on a cruise. So we went back to old-fashioned methods: Local newspapers, hand delivered flyers round about our installations, recommendations, newsletter to existing customers, Freepost cards And these have worked so much so that we want to extend this area and improve what we put down in print. We know what we want to say. We just don’t know how to say it to get best results. We need an expert copywriter, with proven results in B2C, that will help us achieve a steady supply of good quality enquiries. If this is an area you are experienced in can you give me a ring for a chat.
