How to market switching to FOSS and EU service providers?

As some of you know a few good people and I are starting a co-op to help European organizations switch from USA big tech to FOSS software and EU based service providers. Thanks for all the supporting words and early feedback. I'd like to draw from the well fediverse wisdom again.

My hypothesis is that in Europe there is some number of business owners and organizations who want to change (for example they hate Trumpism or want to support local businesses), but they don't know how and would pay for support. That's who we want to reach. It might be a minority, but enough to feed our team.

Do you think it's a sound hypothesis? If so, how can we verify it?
