سلام - فکر کنم اون چک باید شک باشه. ولیکن اگر منظورتان همان چک است لطفا جای doubt را با cheque عوض کنید.
Dear Sir, / Madam,
Thank you for the job you offered me. Please,however,note that the title of your company's main area of activity / business does not match with the job , which you have now mentioned to me. Also as I am not familiar with the circumstances in here , I cannot work / don't like to work with doubt. In fact ,I'm willing to work / cooperate with your company but , some parameters about the main function / business of your company are still unclear to me. Besides , I can help you mostly in management and marketing fields. areas.
Please kindly let me have your clarification regarding my said points.
Thanks and best regards
