Support from firms is of increasing importance in amateur astronomy. Two projects were described. In the first, a company running a winter resort in Argentina was persuaded to hold Halley observation sessions at their site in the Cordillera de los Andes. A similar event was later held by the same company at a new resort in southern France. The second project involved interesting a professional journal for construction engineers in producing a special issue devoted to Comet Halley. This was speedily exhausted, most of the demand for back numbers coming not from the engineers themselves but from their families.
