The Hartnell Marketing Group (HMG) is an Interim Marketing service provider. We service companies that require full marketing provisions for short term or limited scope projects or while an in-house marketing department is developed. We help companies develop a strategy, implement the plan and find and manage agencies and suppliers that can be trusted to produce and deliver high quality marketing and communications that are relevent, work and provide a return on investment. Interim marketing differs from a typical consultancy in that the strategies and plans are actively implemented and managed rather than simply handed over for the company to act upon.
