Hi there!
US freelancer here (Oakland, CA). I am a graphics designer and hobbyist photographer so I think I could help you out. The amount of time it will take really depends on how long the video will be and how many of the assets will be provided or will need to be created, but I am available to work full-time so I will be as quick as possible. You can take a look at my profile to see some of my work. I look forward to hearing from you!
