Don't be discouraged based on the fact that you haven't shot a wedding before. Seeing as how none of these people have seen your images, you might just be better than they are. I know I've seen some work from "experienced pros" that is absolute garbage. But eh, it's all in the eye of the beholder I suppose. I would say your basic lenses would be a 24-70mm f/2.8 and a 50mm f/1.4 That's at least what I brought with me. I also had a 24 mm f/2.8 I had bought. If you have a place where you can rent the lenses, I would do that. borrow lenses.com is great if you want to have it shipped to you. I don't know how far out the wedding is though, time wise though.. But this would be a great thing to do if you have the time and money to do so. I did the same thing that you did.. shot a wedding for a friend and was super nervous.. but instead of doing it alone, I brought along a photographer I knew had photographed weddings before. Many people on this website discouraged me from doing it, but I kept on trucking and the photos actually turned out okay! The bride loved them, and I got a lot of compliments on my use of composition. I also ended up learning a lot from the photographer who helped me and we're now good friends. You never know what you are capable of unless you try. I would say to put out an ad or ask around to see if anyone in your area could help you photograph it. If you ask nicely, they might even do it for free (that's what happened to me!) I would recommend though definitely not doing it alone... that could end up disastrously in the situation that a battery dies (which happened to me twice, but I had a second to take all the family photos!) Although it may not normally turn out this way, my friend was incredibly happy with the shots--even the really bum ones. She gave me $100 for my effort, and recommended me to all of her friends. After that, I was very encouraged, so I started my own business! I still use a lot of the shots from her wedding on my portfolio today (even though I'm new

) So TLDR: Do it. Bring someone else though and make sure you have the right equipment.
