Great just keep in mind there is more ahead than you currently think there is, especially in equipment plus the learning phase of all the gear and how to recover gracefully when a camera or lens bites the dust while you are working. I use 2 D7200's currently but I had a backup that was tried and true that I used for a year but a year later when I needed due to failure on a D7200 I found I had forgotten everything I knew about the backup camera. During film days it was easy as it was all mechanical and most cameras needed no technical info to operate Basically good with a Hasselblad you are good to go with a Bronica SQA. In digital you have so many buttons and dials to use that if not used often or at least sometimes you forget what they all do. My failure that day was that a setting on the D7200 reset all my settings to default mode which just confused me as I was making ready for an opening sports shot changing to the other body stalled me a bit but then I started to remember and got the shot I was prepping for. To solve that problem I bought another D7200 and set then both to the same settings. After business classes do take a full course in still photography. The PP of A has many courses in photography take them.

If you are serious you might get a better body like a D7200 which fives you a back up chip in the camera in case the first chip fails at a wedding. I would also advise you have 2 D7200's. as if a body fails you have a back up there too. Then You will need good flash guns for the wedding at least two radio controlled units and not the little ones you get for $60 or $70 a pop. I have been a pro-wedding shooter mostly during film days. I know all the ins and outs and the bridezillas who thought I was the nicest guy at her wedding.
I suggest unless you have the gear and know how to use it you take a course in business and a course in wedding photography. Also a Join PPofA (professional photographers of America) Just in case you have a problem with a wedding. The insurance they cover you with pays off if needed. Retired now I still work as a photographer in just as stressfull situations as wedding were as a yearbook shooter. I cover sorts and activities in high schools. I meet the year book kids from time to time and usually I hear how much they like the shots I create. As for the studio I shoot for I see them weekly to upload several thousand shots from my drive and sometimes a check then go home an await a new schedule for the week.
I have seen the amatuer turn pro and I have seen the lousy group shots they make. You really will do the Pro industry much good if you learn all you need to learn before you call yourself a pro. I won several contests then turned Pro but I knew then that I needed more training and made sure I got the training both from schools and from the Pros I hooked up as a part time wedding assistant for 6 months or so to learn. I see a lot of names in the phone books over the years that opened shop and were close the next year which gives us real pros a bad name. One studio I shot for vanished and I still had the film for 2 weddings that I shot and no payment for either. I saw a news story on that studio and called it. both brides were sent to me and the TV station paid me my fees the studio should have paid me for the film. The brides and the TV station loved me for being honest but all I cared about was that the bride got her shots that I made. Like I said I have seen many start and many fail mostly due to lack of knowledge and lack of customer care.
