Simple editing of 12 videos

I am setting up an online science club, and need someone to help me with some simple video edits, including
- Jump cuts to get rid of mistakes/ retakes
- inserting images/ videos (which I will send you) into the video
- potentially adding an intro (similar to my youtube videos https://www.youtube.com/watch?v=thvrY00Yegs&t=2s)
It will be 2 videos per week for 6 weeks, so 12 total, each 5-10 minutes long.

I would be interested in prices for the package of work (and the price with and without the intro, if that is different?), or a per video quote.

Thanks
Ginny
