The only thing it proves is that a lot of people are shopping more for best price than for best quality. It's always that way. You're going to have to get used to that. Shoot what you can and let your reputation grow. There is no substitute for word of mouth advertising. You will begin to get the couples that really want your style of shooting and will not mind paying fairly for it. Meanwhile, there will always be friends and relatives with cameras that are willing to do the job free or very cheap. Sometimes they have talent and ability, many times they don't. Let your portfolio and your website speak for you.
Join your local pro photographers association and put a little networking into it. Decide where you actually fit in the pricing scheme of things and then set your rates and hold to them. It's a competitive world. Len * There's no place like 127.0.0.1
