As a first step, consult with an immigration attorney. As to the overstay, because he overstayed more than one year, he is not eligible to come back for ten years. However, if you get married and file immediate family petition, he can file for a waiver and still immigrate to the U.S. If you do not want to get married now, you can file fiance visa and you have to marry within 90 days from his time of entry to the U.S.
