Generate a list of 30 Conferences for a Mgmt Consultancy to potentially attend

We need create a list of conferences across Western Europe (excluding Germany) that might be suitable for our company to attend or sponsor. We are looking under 2 broad categories:

- FUNCTIONAL FOCUS: aligned with general management functions (including, but not exclusively: product management, inventory management, complexity, manufacturing, supply chain, operating model, efficiency, network optimisation, safety, operational excellence, high reliability, etc, etc... happy to clarify further)
- INDUSTRY FOCUS: industry bodies that host annual conferences. We are interested in Energy (and all sub-sets - oil and gas, renewables, nuclear, etc.), retail, FMCG, Telecoms, Mining, Utilities, Manufacturing, 'industry', Public Sector.

Info required on each (should be available from their websites):

- Who is attending - we NEED conferences with decision makers that can buy consulting services (CEO's, C-Suite, Operations Managers, Plant Mangers...) - if not, don't include.
- Speaking opportunities – some conferences only allow consultancies to set up booths, which we’ve found to be ineffective in the past
- Cost – Less than GBP 30,000 only; otherwise exclude

Please present your findings in a table - preferably in excel.

Please do share your progress after you have done a few (<5) so we can check we're on the right lines

Many thanks!
Tom
