Could you please correct the following text for grammatical errors?
Before accepting my current job, I consulted with you about the potential date I could join this firm on. On which, you suggested that I should join it immediately, as it represented a better opportunity for me. Had you insisted on a pre-departure notice, I could have delayed my joining date. Moreover as a courtesy gesture, I sent in four prospective candidates to you as my replacement.
