Logo critique and ideas required

[basils57]

Thanks for these folks. In answer to mwenz, the original intention of the green rectangle and cross was to use the green to suggest safe and the cross can be aligned with health - abstract and contentious, I know. But we feel that that image has become symbolic, could be we are misreading that?

Being a consutancy however, we want any new logo to provide an impression of professionalism as much as anything else. Rik's circular and angelise's idea hold some appeal - probably because they move away from the current - but does the flag convey professional, and is the circle too much of a change away from a rectangular shape? I also like Rik's extension of the current.

My remarks probably explain why I asked the suggestions in the first place, being an obvious amateur on the subject. But your comments are certainly stimulating.
