It's important to not blow all you money at once on brand new camera but instead to buy a cheaper camera to learn from and grow because most of the quality comes from lens, lights and the content in the video. The best two cameras to start off with would either be the Canon T7i or the canon Sl2 which is a cheaper option than the T7i. The T7i basically has better autofocus and is little more durable. Though they both have the same sensor and would get the same result.
Here's a pretty solid kit for the the SL2 http://amzn.to/2gIIjnu
Your going to need some SD cards and I recommend Sandisk because they have lifetime warranty and anything happens they will replace just do through away the box. I actually own a couple of these http://amzn.to/2zVyavR
Heres a great Mic for the price http://amzn.to/2i9DoMI
