Look for photographers in your area. Bad news travels fast so if they aren't the best at what they do, people will know about it. Be open and honest about your budget. If you really can't afford a professional photographer, ask them for a referral of a professional with lower prices but with a similar style. Photos are what capture the memories of your special day that you'll have for a life time so this is one part of your wedding you don't want to mess up!
