How can I record my DJ mixes to my ipad?

I am trying to find a cheap viable solution to recording my DJ mixes to my iPad. The amount of external sound cards and apps is extensive and all range in price but choosing the right one is proving to be a mine field. I want quality but simplicity at the same time. Also I want to be able to upload to mix cloud, soundcloud and any other sites right from my ipad without transferring to my macbook (if that's possible).
