Hi,
I would be available for more than 20 hr/month if this project would require it.
If it is a classical power point presentation of about 30 slides, depending on complexity of the slides (animations, sounds, etc) it should take up to one or two working day to create the video. If you require creation of additional assessments on the LMS platform, I more than willing to work on that. I have extended knowledge on Moodle LMS and working with different kind of assessment activities.
I would like to know which LMS are you using and what kind of assessment to you need. After looking into the power point presentation I could give you a precise time frame for finishing this project.
Looking forward to hearing from you,
Dusan
