After Effects / Smoke moving image FX Designer

Hey, I'm a film director, just about to release my directorial debut feature documentary. Entirely self-funded and 3 years in the making, the film has just been signed to one of the best festivals in the world and got a distribution deal. I'd want to keep the title and content under wraps for now; the job I need done is a very simple, single shot manipulation for someone who knows After Effects, Smoke or similar VFX software. I need a person removed from a backdrop of a 1920/1080 shot that lasts about 5 seconds. The budget I have is reflecting how small a job this is, it should only take a few hours and I can spare up to £60 for it. I need it done within a couple of days, deliverable in 25fps prores4444 both ways. Should be quick and easy though experience is obviously necessary as to make it look seamless. Thanks!
