Tunnel Ventilated Housing Barn

I am looking for someone to conduct a few CFD modeling scenarios for an animal housing barn to determine the optimum ventilation strategy. The proposed animal barn is 137' x 525' and I need airspeed/airflow modeling indicating airspeed (MPH) throughout the barn at 5' ht. Attached are the floorplan and section of the barn. It will be equipped with 12 - 9' industrial fans each producing 129,000 CFM (1.548M CFM Total) at .16 inches of water column(static pressure). Eight additional fans (100,000CFM each ) will be located in the barn to further boost the airflow in desired locations. The output model should be a color coded map of the barn indicating the airspeed at 5' throughout the barn relating especially to the different lanes of the barn indicated in the section. Interior building columns, fencing and equipment are not to be considered for the modeling task. I need this to be accomplished soon with the results sent to me. Please propose estimated time to fulfill and rate. Also please specify what type of file you desire to work with for the initial barn design. Please also reference any HVAC airflow work you have completed in the past. Thank you Glenn
