I would dedicate my free hours, and I have a lot at the moment, to completing your project for you in the smallest time frame possible. I would be using Adobe Premiere Pro (cc 2017) and could return the completed project back to you in what ever format suits you best.
I may be new to freelancer but with that I bring an eagerness to prove myself and this will be reflected and visible in my work. You have given a clear guideline of what you expect from the video and I can create that for you. As for confidentiality, once the project is complete I will delete all files related to it, just to be safe.
Thank you for reading my bid, I hope we can work together now, and in the future.
