Wedding planner.

Hello beautiful brides, so I have a few questions, I can’t seem to decide if I want or not a wedding planner, here are the reason. My fiancé and I don’t want to over pass our wedding budget, wedding planner might be necessary but they are a bit expensive, a second reason is we are buying a house before the wedding, so far we have stayed in our budget. I done majority of the work. Booked ceremony and reception location, booked photographer and videographer, i booked hair stylist and makeup artist, DJ, got my engagement photos done, already have a my save the date magnets. Do I need a planner for further things or it’ is not necessary since I done almost everything?
