Working primarily with the fs700 and 60d on canon and samyang glass. Bronze level steadicam operator, flying a scout.
Time and Time again, the answer to this question is buy GLASS. It's safe to say only having the 18-35 isn't much of a range. Go buy a box of the rokinon/samyang cine primes, amazing lenses and give you a range and quality.
If you aren't interested in super slow mo or low light then I'd advise to pick up a second hand c300. It shoots beautiful images.
The ursa mini, although it maybe at final output produce a nice image, its awful to work with and really requires a crew to use. Those V-Lock batteries aren't cheap either. And think of the extra costs in post production.
If you're not interested in the 4k the c300mk1 is the best choice, I'm a fs700 owner by the way.
Or you could get a second hand Red Scarlet for about 7.5k, since you already have everything else apart from lenses.
Would something like a c100 not be better than another dslr?
Means you can use your glass without adaptors, and will give you profesisonal mic inputs too, alternative options would include a second hand fs700, fs100, you've got to question if your clients will notice 4k, if its a request get a6300, but its not more professional by any stretch.
Keep your dslr as a B Cam and get something to compliment it, and give you more options, c100 would be my shout!
Personally, for the stuff I shoot, I'd look at a second hand fs700, there's a lot of them floating around these days and some rokinnon glass. I'd go with a decent a tripod and if the budget was there a ntg2 shotgun mic, I'd buy all the periphials like batteries etc on the cheap. Don't forget a good bag/case too.
You get high frame rates, a decent codec, a future proof camera with the 4k addition at a later date if you so desire, its a real value for money camera.
Alternatively could go wild a get a a7sii with more glass, tripod, cage and filters. But the first option is what I've got, and I'm content.
Personally, going from a 1200d to 70d isn't a big enough jump. Its not going to give you more frames, not much of a better codec or bit rate or high frames. I've used the g7, it's fine, 4k is overkill.
I'd look at just buying a couple of primes and really using the 1200d body until you can feel it can do no more, and then back yourself and go for a gh4/a7s either with a loan or by doing shoots some corporates.
I'd go for a 35mm and a 85mm rokinon, with a ND filter/polariser filter, if your buying online, eglobal is great, i've bought from them before and prices are a lot cheaper. A good tripod can go a longer way too.
If I was you I'd go for;
18-135 or the 24-105 (this gives you the option to have a shallow depth of field unlike the xf300, you probably won't be zooming so in the majority of cases your be at a fixed focal length during a interview.
Couple of the cheaper amazon Canon BP-955 (non brand)
Manfrotto MVH500A Fluid Drag Video Head with MVT502AM Tripod and Carry Bag
Rode NTG2 Kit with Shock Mount and XLR Cable
A couple of class 10 sandisks
You might well have enough for a set of radio mics too.
I'd also consider a couple of led panels for lighting too.
