Hi, I could do this job for you.
Everything is very achievable- however, with the lighting flickering, it can sometimes be hard to fix. It all depends on what is causing the flicker and why. However, I could do everything I can to help you out with this, and try to diagnose the problem.
Freelancer.com employs me to film, produce and edit their case study videos and also a longer, feature length documentary so you should too! Here is a link to some of my filming and editing work: [login to view URL]
I hope to hear back from you, and if not, best of luck with your project!
