Hi, I could help you make a high quality instructional video for your application. I've made some instructional videos before that are on youtube (one of them has almost 100,000 views). I have a very high quality microphone and high quality recording software.
I'm also very experienced with video editing and using programs such as Adobe Premiere, After Effects, and Photoshop.
If you're interested or have any other questions, feel free to send me a message!
