Green screen keying: Battle Gaman

Hi, looking for someone to who knows their way around AE to key, 203 video files (Dur. range 5sec-30sec). 500 gb data. Shot RED, outputted as ProRes4444. Need outputted with alpha channel, so I can compile elements together to make layered scenes. Or create an after effects project with the work done inside so you don't need to export. But if that's the case maybe create some proxies for me to use. This is for my masters project, it will be a short film aimed at festivals. I am a producer/director that knows my way around Premiere Pro, but I've tired keying and am not good enough at it. The lighting is good, but unfortunately I wasn't warned against wearing white in some scenes so their is spill. Also, the focus is a little soft at times. All shot on a tripod fixed frame 20mm. All in high frame rate. I think it was 120fps (we filmed 18mths ago, so a little foggy on details). The key doesn't need to be perfect, I can use other elements to hide areas in the compile. If you don't break the bank, I might get you to continue working with me on the comp. The actual film is trying to be like a moving fresco, very 'bosch' nightmare meets digital VR painting. I'm in Melbourne, Australia. I was hoping to post the hard drive rather than upload 500gb data, and attempt to download again. Any other questions hit me up. Cheers Auryn
