Financial ratios for companies in Saudi stock market

I need someone to help me calculate financial ratios for multiple companies in the Saudi stock market. The specific ratios I need calculated are the profitability ratios.(ROE, ROA, Net profit margin, EPS, P/E, P/B and assets turnover for 18 companies. They must be calculated for the calendar year-end. This will serve as helpful data in my research and project, so the accuracy of the information is crucial. Someone with a financial background and experience in this area would be especially qualified to handle this job.
