This is going to be a hot topic! I'm going to say something you don't want to hear - but I hope you won't hold it against me if I tell you the truth (as I see it).
Look for another career.
It sometimes seems that every third person with a DSLR these days wants to be a wedding photographer. Competition is beyond fierce - it's absurd. It's possible to succeed, but it will be very difficult. And remember, getting one or two free gigs isn't success. If you want to do this seriously as a business, you need to make money. That means you need to be able to charge a fair bit of money for a service that many, many other people are willing to provide for free or nearly for free. I could expand on this theme for a while, but I'll stop there.
But I want to add one or two related points.
I think photography is a bit like playing the guitar. Many people find it very enjoyable - and many people find it easy enough at first that they think they're good at it. Their friends tell them they're good. So before long, they start dreaming of fame and fortune. Amateur photographers start thinking, "I could make money doing this!" But the only market they can think of is weddings. Why is this? Because it doesn't take any credentials to talk a bride into hiring you. But it's rather harder to get National Geographic or the Detroit News or Ford Motors or Vogue magazine to hire you. All these photographers "doing weddings" are like all the guitarists appearing in pizza parlors and bars around the country. They may be good. But turning this hobby - this passion, if you prefer - into a full-time job is very difficult. They're just aren't enough weddings with $2000 budgets to support half of the people who want to do weddings now.
And why would you WANT to do it?
People typically say that they "love doing photography", they "have a passion for photography." That's great. But succeeding as a businessman isn't about passion or love, it's about competence and business ability. A person whose job involves shooting weddings has to be a business person first, and a photographer second, otherwise they'll soon find that they're only a photographer. Now, the business part of wedding photography is, like the business part of nearly everything, a pain to deal with. As they saying goes, money changes everything. I mean, if your passion is business itself, then for pete's sake, get an MBA or do something that might make you rich, instead of just barely making you a living. And if you think you can deal with the business side of wedding photography, understand that shooting weddings is WORK. When people pay you to take photos, they expect you to take photos they like - not photos that YOU like. Shooting weddings involves real risks: People may be mad at you if you screw up (and you WILL screw up now and then). Shooting for money changes your attitude toward working with your camera. Every wedding photographer is, to some extent, just a few steps away from the person who shoots portraits at Wal-Mart.
I think that, for a large majority of people who have discovered that they love taking photographs, the best route is to pursue photography as an avocation, rather than a business. Some of the greatest photographers in the world are not making their livings primarily with their cameras, and many have jobs that aren't related to photography at all. Photography for them is like poetry has almost always been for nearly everybody, something done for love rather than money.
There's a great saying about photographers: "The amateur thinks about his equipment. The pro thinks about the money. The master thinks about the light." Everybody needs to decide which of these things they want to think about. And while you're at it, go through the great histories of photography and count how many wedding photographs you'll see in there. (Hint: If you count on your fingers, you won't have to use both hands.)
If you want to be a business person, and you can see a business model that will work for you involving photography, go for it, and good luck to you. But if you love photography and want to take photographs, then save yourself some grief and take photographs. Enjoy the freedom to pursue your passion on your own terms.
