It sounds more like a custom build than anything. I'm not sure what country you are in, but if it is Canada,
www.draganfly.com would be a first step. I know there are sites that sell everything to build your own, but again with the software, that is where you need a tech guy that can write for you. Now you are looking at the price going way up.
Let me be brutally honest with you. I'm a cheap ba$t@rd that's part Scot, English, and the rest a mix of German and some other crazy crap. That makes me of the cheapest kind, it's in my DNA. To me if it cost a lot, it better be freaking heavy. That's always been my guide and it's worked.
Drones are pricey to get into, but we are getting it for so cheap in reality. And how's that?....well we didn't have to invest in any R & D costs. We get them for the "Here you go" price. I'd rather some other phucker spend their time and money on figuring it out and take the "Here you go" instead.
So don't end up being cheap like me and risk your drone over a start up or trying to figure a way around a couple hundred bucks. Don't get me wrong, a couple hundred is a lot of cake, but once you get into drones more, you will find that to be a low cost on things we need after a crash or upgrade.
I like Yuneec and the way they have all their parts mesh together for what your own build becomes. People do customize their drones in their own way, but I only do it with what they have available.
