My wedding is in August so it is going to be outdoors at my uncles farm. We have booked event tents through Ellen Wilson. They set up the tents, take them down and have lights. You can find her on Facebook.
We have our photographer booked with casting moments photography and it has been great dealing with them so far. They have many different packages depending on what you are looking for and very reasonably priced.
We are just having a midnight lunch no formal supper so we aren't hiring a caterer at all.
That is pretty well all I have figured out so far! Hope it helps!
