Hi, I'd like to help you but ask you for more explanation.
1. Do you need just one video or for each product/course/session?
2. Do you need video tutorials explaining features of your portal (e.g. how to enroll in the course, how to publish teaching solution etc)?
3. Do you need specific voice over (for video, e.g. male, UK accent)? I have nice English voice and can mimic UK accent but usually good female voice is needed - but that can mean $220 per studio recording hour (I cooperate with excellent studio via Freelancer.com).
I'm not expensive - the rate is for my output hours when I really create, edit and tweak video (preparation). Any reconversion for better quality, text typo fixes and possible learning are not counted for and are usually 2-5 times more hours, depending on the project.
Otherwise I do create, help with and implement multimedia e-courses for adults with Camtasia Studio, PowerPoint, Articulate Storyline and other software.
I would love your feedback.
Regards,
Matt
