Assalamu alaykum and welcome to the forum brother Yusuf,
Ma sha Allah, this is a noble goal. You should look for a teacher who has knowledge of the Qur'an who can guide you in the process of memorising as well as reciting the Qur'an correctly. May Allah make it easy and help you to memorise His Book, Ameen.
Asalaamu Alaikum. As you have already been advised you must memorise the Qur'an via a teacher face to face in person if you possibly can. If you cannot then the next best step is to do so online via a video streaming platform. Please also refer to the following link which contains plenty of encouragement, advice, help and guidance on memorisation of the Qur'an:
