Hi, here is my submission for your review. I made a mirror image of the 7 to create an upward pointing arrow -- representing productivity. It's simple, but because the 7 shape is incorporated, it make a statement about your company's product. I hope you like it! I can easily make variations and color changes if you like the general concept.
Having been a part of this contest for the last four days, I am amazed that you can think of ideas like this so quickly. Your graphic is indeed very powerful and it may have a place in our needs.
We have had so many entries for the primary logo we are still sorting through them, and I may want to continue to have a conversation with you regarding how we might be able to use some of your work as well.
I would love to see additional ideas like the one you have shown. Your work is incredibly clean and pure. It appeals to the message I am trying to convey.
