Covesting Educational Videos

Hello, I work for a startup in the cryptocurrency world. [login to view URL] is our website for reference. We are creating a knowledge base for cryptocurrency to go along with the rest of our project. We are intended to make about 15 videos, all purely information. We have the scripts, although you can 100% have some freedom with how you present it...it doesnt have to be word for word for instance. Our other requirements for the video would be to overlay our logo in the corner of the screen. Videos would range from 2 minutes to probably around 4/5 minutes max. We would like to do all of the videos with one individual, and we're contacting the best producers on freelancer, fiverr and a few other sites. We wanted to know what the cost of this would be and how fast you can turn around the project. Whoever we choose will also likely gainfurther business with us as we continue to produce more knowledge related videos about cryptocurrency. Depending on how the knowledge base grows is, we may even require weekly videos in the future.
