Selling letters

You need to write a few “selling” letters.
We sell industrial design services in a poorly developed region.
The problem is that the need for design is already there, and the awareness of this need, and the understanding of how design can be incorporated into existing business processes, is only just emerging.

Letter No. 1: “Customer – Company”
Focused on the heads of medium and large manufacturers (for example, automotive or furniture production) in search of mass-serial order, so it should be moderately strict in writing, but do not forget about a one-time exclusive order (for example, arrangement of a chain of restaurants / cafes).

Letter No. 2: “The Client is a Man”
Focused on the customer or sponsor with good income - ready to buy the product (for example, a yacht, an airplane or an all-terrain vehicle) and just be a sponsor in the production or organization of expeditions (record events).

Letter No. 3: "Samopiar"
A simple letter to send to local newspapers/magazines/radio/TV with an offer of yourself as an author of articles or a speaker on the topic of design and all the ensuing.
