I need a Content Strategy and Editorial Calendar for 6 months to promote GAS

Hi i'm after a content marketing strategy with a content calendar for the next 6 months for a company that sells calibration/span gas. The company doesn't have a content strategy for this product range at the moment and very little online content.

The gas cylinders are sold online via an E-Commerce website and also via an account managed service based in the UK and Singapore (we have two offices) You can buy individual units or in bulk.

The aim of the content strategy is to promote the company as the leading provider of calibration and span gas in the WORLD. We have a compelling value proposition and an already active customer base.

We mainly target the Marine industry but other industries use this gas to calibrate and test their gas detection systems.

To confirm i am looking for a 6 month content plan/strategy. this project does not include the management of social media or content writing - just the plan and schedule.
