Help! Can’t find brunch catering for 50 people under $800!

I’m getting married and a little over a month kind of a last-minute thing I need brunch. We’re having a morning wedding I’m looking for a brunch catering that doesn’t cost $1 million trying to do this as cheap as possible without having to make everything myself. I don’t have family except for my aunt and grandma pretty much doing this whole thing so any ideas would be very helpful.
