International Excess baggage to Japan

I am scheduled to leave my home airport at Atlanta, Georgia, in the United States the middle of next month. Since this trip is due to a business meeting that I am required to present various proposals, samples, and so forth, I must take a great deal of extra baggage with me. So I have posted my inquiry here in anticipation of connecting with a company who handles international excess baggage to Japan. The baggage includes six additional bags plus my two carry on bags, and 3 suitcases for personal use. If your company can offer the better arrangement, I will gladly ship all of my baggage less the carry on bags. So please tell me how you base your charges. Do you charge by the piece? Or do you charge by the weight? Also, can you deliver my baggage along a similar schedule as my flight? Do you deliver my baggage direct to my hotel, or would I need to pick it up at one of your offices? Please include as much information as you can, as I would really like to have my travel arrangements completed within the next few days. Thank you so much.
