Gender Reveal Help

So ladies, my husband and I are finding out the gender of our sweet baby this coming week. We decided that we wanted to find out just us two. I still want to do something special. The only thing I’m struggling with, is that nobody in our family/friend circle wants to know what it is before our party in a few weeks - so I don’t have anyone to help us set anything up for us to actually be surprised. Do you have any ideas?? I was thinking of giving the envelope with the gender in it to a cake decorator and just having them write on a cake what it is, but I just wanted to see if any of y’all had any better ideas??? 🙂
