Need some recomendations.....

My eparty is in a couple weeks and me and FH decided that we want to hire 2-3 people to serve the food and just clear the tables. We were going to get this as a little thank you to our mothers since they are making ALL the food for the party. But the people we know who do this on the side are already working at another party

So basically, does anyone know where I can find people to do this? And we are also looking for a bartender. I have no idea where to find someone.

TIA
