You can learn from this guy who designed his own controller some time ago, now he runs his own brand a some great products: http://zeva.com.au/Research/ControllerDesign/
But I can tell you from own experience: Designing your own stuff, like a high power motor controller is not a Cheap thing. You will require lots of trial and error, learn and explode lots of MOSFets or IGBTs and that requires time & money, but satisfaction once your prototype is running smooth and nice is huge. If you are looking for cheap stuff (Cost), then you can only choose one more the two left: Time or Quality. But they'll never come all three thogether.
