Like this for simplicity; ask to explore variations including the icon to the left of the type. Horizontal logos work well for websites, as they reduce the vertical height required to hold them, making the page header more efficient. Could the square container around the icon be removed? Could the three paths of the icon feed into the top middle and bottom of the "F"?
I like the direction of #52 + 53. The font is very similar to the FedEx logo, though. Would you be willing to experiment with one or two different font directions?
