I run a small online storage business and need to approach all the major self storage with a business proposal for a partnership.

I need to make an approach to all the relevant executives in the storage industry and email them my proposal to them.

The task

1. Identify top 100 self storage companies in the UK (you can go to Self Storage Association for this or google)
2. Identify the person or persons responsible for business development
3. Create an Excel spreadsheet with their names, role/job title, emails, Linked In profiles (and preferably their direct phone numbers if possible)
