Hi There Hope you're doing okay, Umm i have no problem at all with the video editing part, the transcription part is what's going to take up the time, however if provided the script and i won't have to put it manually myself, i can say it would take about 2 hrs per video with a length of 7 mins like the one in the sample ( Render time included and all )
Because of the length of the video here, as for 1 hr per video ( then the video must be about 3 mins long to be done in under one hour )
I would love to work with you on the project and produce a super cool outcome. I use adobe premiere and after effects as well
Feel free to text me, Seriously, i'd love to do it :D
