creative logo design

We need a custom logo design for a freight brokerage company. This is part of the transportation industry. Freight Brokers are intermediaries between manufacturers and trucking companies. They acquire freight that needs to be transported and they contract the appropriate trucking company to get it to its destination. We need 4 or 5 initial concepts from which to choose. Please keep in mind that multiple edits and/or revisions may be required. We need at least one concept to contain a truck but the truck needs to be realistic and true to life, not cartoonish or appearing like a clip art image. Another concept should contain a road or any other creative way to relay motion or logistics coordination. Please ensure the font is unique and different in all concepts so we can select.
