Hello,
You need to consider very seriously investing in additional software for photo/video editing. And improving on your skills. Otherwise you and your boss may end up dissatisfied with this investment real quick.
Current generation iPhones/Android devices has lots of things going on under the hood before you see the picture/movie on the screen. And with the camera no matter the kit price, to match and exceed the phone IQ ( image quality ) you need to invest much bigger amount of additional time and effort.
Two examples:
HDR with photo and movies - every phone-camera today has by default very good HDR enabled in both picture and movies!
Low light - again every camera-phone has integrated stacking, noise reduction and other techniques which basically with zero effort provide you with night vision like pictures.
So if you have no skills and/or time and money for the software better stick to the iPhone and work over lighting, composition and editing alone.
All this come to say, just buying new "real camera" will not automatically provide you with better results. And you will need to spend much more time and effort with software, to match and exceed the phone images.
For example you can very easily exceed the phone IQ with resolution - but you do not really need very high resolution as you are publishing mainly on-line.
And it will be very hard to exceed the phone IQ with video and photo HDR. Which is like shooting in the bright day, sunset/sunrise, many different lights and etc.
It will be very easy to beat the phone with different focal lengths - much bigger zoom, better work with flashes, macro, ultra wide and with some other conditions.
If you decide to go the camera way and learn it, it will for sure be rewarding, but you need to add to the budget Adobe CC subscription, or some other creative tools for both video and photo editing. And you need to have at least 3-6 months until you start getting something useful from the camera pictures and maybe even more from camera videos.
It is clear that your budget is not big, and you have no idea so far what exactly do you need, so most probably will be good to start with some kit with two zoom lenses. You may need to consider adding tripod to the kit especially for video work. But as said already these lenses are "slow" and not easy to be used in less than day light conditions. but you can use them to figure out what focal lengths do you need. And then invest in more targeted and "faster" and expensive lenses. Or other options is to start with one more expensive lens if you know exactly what do you need. With Canon you can also use adapter and use old EF/EF-S second hand lenses.
But aside to all I can not stress more over the need for additional software and efforts to make this purchase useful.
Hope this info will help you!
