Looking for suggestions on mapping hexacopter with a6000

I've been flying a 3dr x4 with a sony a6000 strapped to the bottom for mapping and photogrammetry. It's been good to learn with but it's way overloaded and I get 5 minutes of flight time max.

I want something that could lift 700 grams (sony a6000 camera, lens, and simple mount) that would maximize flight time. I'd be happy with 15 minutes of usable flight (so let's say max 20 minute or something like that). I'd like to stay with pixhawk. I've thought about an s900 frame with a pixhawk controller.....but I'm looking for a rtf or almost rtf and it seems a little involved to get that together. I'm learning all the uav intricacies but I would rather someone do the main calibration up front.

Any thoughts on what a good used (or maybe new) setup would be? I could spend up to $3k, but would rather in the sub $2k range.

If you're interested I can build something for you. I'm flying my A6000 on a custom built 850 (though truthfully I've been flying my NEX 5T more so far this year cause it takes just as good of pictures while I risk 1/10 the amount of money in the air). I get about 21 minutes of working time (28 minute hover test but actually moving around working I consider 20 min of maneuvering doing great)

Note this is with the camera on a soft isolation, but otherwise ridged mount. Still building the brushless gimbal and expect flight times to be reduced significantly, hoping for 12 min flights once it's on there.

I regularly fly a pair of Tarot 810 frames with a single axis gimbal with a large vibration isolation plate, and Canon eos-m cameras the weight of the camera payload varies a bit depending on the lens but is right around 700g. I have used multistar 4830-420kv motors and more recently T-motor MN4014-400kv, and MN5208-340kv motors. With a Multistar 12,000-6S battery I get about 21min flight times, but I have substantially more lift capacity and could easily add more battery for additional flight time.

I find that I can typically fly about 15min so having some leeway makes life easy, but on occasion have flown over 21min to get my work done without multiple flights and still haven't used 80%. I like the 810's despite the fact that it's probably overkill because I don't have have to stress if it's windy and the complete package is pretty rugged and easy to service.
