Convert my Word Doc to Kindle Format

Hello everybody! I have a word doc that I want converted to Amazon Kindle format. The file only has one JPG image as the cover and the whole file has numbers and letters as bullets: I, II, III; 1, 2, 3, 4; a, b, c,d. I know you understand. I read that a lot of bulleted or numbered text does not convert well to Kindle. Is this true? Anyway, I need somebody to help me, keep the confidentiality of my document, and provide me with the best conversion possible. Let me know! Thanks Luis Valle
