These are presented with the first versions here at the top, the later versions below, and the original proposed logos so you can see 3 stages of development.

Some of these are way too busy and “out-there” but at this early stage I was just throwing things out there and hoping they would seize on elements they liked, which did happen.
These first 4 are ones they had used in the past and wanted to use for a starting point:
