I would really hate to see your wedding day ruined becasue you were looking for an inexpenise photographer. Look at the photographers work and talk to him. If you like his work and what he has to say then book him and find a way to pay him.
Most photographers have payment plan for the wedding photos.
Also they have packages. Pick the one that fits your budget also have people that want to get you a wedding gift buy a gift cert. The food, cake, flowers, and the dress will only be for that day, but the photos are for a life time. Congrads on the wedding and hope you find your photographer.
