psychometric test

I am in need of a korn ferry psychometric test that is a combination of verbal, numeric and logic based multiple choice questions within a 1 week timeframe. My project requires an accurate and comprehensive psychometric assessment of my candidates and I need a well-crafted test that can provide this. I am looking for someone with the skills and knowledge to design an effective, reliable test with extensive knowledge of psychometrics and ability to deliver within the given timeframe. The results of this test will be used to evaluate my candidates and will need to be accurate in order to make appropriate recruitment decisions. If you are an experienced psychometrics specialist and have experience designing the type of test I need, please let me know. I am looking for someone who can create a compelling, comprehensive and reliable psychometric test in a timely manner.
