Galleypower,
There are many companies who will compute the airfield analysis for your company's airplanes. Flygprestanda AB, Condor, Jeppesen and no doubt others who's names escape at the moment. Contact one of them and they will ask you to provide your tailored performance parameters, thats aircraft type, engines, configuration, weights etc.. They can usually do this fairly quickly, but will be looking for you to enter into a contract with them for their services.
Most of these companies will have access to the obstacle data for each the airport runways you need.
