How can a Muslim woman marry if her family members are non-Muslims and cannot perform the role of the wali?

Me and my fiancé are planning on having a nikah soon, but I have been researching the topic and my parents and family are all non-Muslim (I have converted to Islam after meeting my fiancé). But I need a Muslim wali with me when we do the nikah, so I was just wondering what I can do? And how can we have a ceremony after the nikah that my family can attend if they can not come to the nikah because they are not Muslim? I am very confused and I hope you can understand what I am trying to say, I would love for my parents, brothers, uncles and aunties to be there because it is a special day for us.
