@michael I should be clear: I'm not looking. Last week, I spoke to two people. One a prominent staff member in a university, the other the director of a large arts organisation. Both keenly asked me to suggest open source alternatives to Google/Microsoft.
I could give them information, but I know how procurement works in large orgs. What they need is a consultancy that can offer a package as an alternative to existing services.
It sounds like you may do some of this. What is your company?
