Creative wedding photography is something that doesn't come easy. You could have the best camera gear in the world (whatever that might hypothetically be) and be a complete failure at it.
The main ingredient is your self confidence. When someone approaches you to buy your services, don't try to sell them the camera you use. You sell them the person you are and the way you can relate to them. THEY are the most important part of the deal, not your camera. Buyers just want to feel they are the most important people in you life for the day they hire you. They don't care about the camera you use, but they care about how they are treated. You treat them right, you get referrals, treat them bad and you won't be in business for a long time. And you have to learn how to direct people, place them in a spot and make them comfortable or put them in a certain mood, this is probably the most important tool you can have in your toolbox.
Second ingredient is the way you know how to use the light to make great looking images. Wether it be natural or flash, you've got to master it and know how your camera can translate what your eyes are seeing to a single picture. This is something you learn and keep learning.
Oh I could go on and on. Photography as a profession that can be learned, not bought in a camera box. If you think you can sell more jobs showing off your gear, you might be at risk for a hard landing when the work doesn't come in regularly. People shopping for a wedding photographer will look at two things, the pictures in your portfolio and the person you are. It either clicks or it doesn't. The camera you have around your neck doesn't mean much to them.
