#10 Could you try one with the same graphic, but the font more in the style of #12 (side by side) with the line between? With a space between R G and C. Also, could you try the same above, but have the maple leaf graphic to the left of the words?
#11 I like that you incorporated the hard hat. This one really stood out. Could you try this one with green instead of orange to see if it works with green as well?
#10 I like that it shows that we are a Canadian company and how you incorporated the 2 people. I like that you added the detail of one person with a tie and one with a hard hat. It is simple but conveys a great and friendly message.
Is there a way to line up the 'Staffing Solutions' in #56 like it is in #40 so it looks more square and lined up? I am not sure if you line up better if it was in capitals instead?
I am wondering if you could try #56 with the 3 elements that are inside the leaf (the 2 guys shaking hands and bolt), but instead make the leaf a different shape. For another idea, maybe in the shape, instead of having the bolt above them, you could incorporate power lines like this
But maybe don't make it really obvious by using the towers. Perhaps you could use the wires and if it needs it, the edge of the tower? This way work instead of the bolt in the maple leaf as well.
Just throwing out ideas, feel free to do what you think looks best. :)
