Edit my next 25 videos

I am making short business videos for my YouTube Channel. I want to get my channel up by August 12th with at least 25 videos completed in advance. Then I will be adding more videos (up to 5 per week for 2-3 months more) I will provide 25 short 2 minute videos that will need:
a) a pre-made intro to attach on the front end
2) some miscellaneous text messages to add to the video (1-2 per video)
3) add a short pre-made audience reaction video to the end
4) add 6-7 pages of text for credits

I will send these by google drive with each video in its own file and I will send them 5 at a time. Preferred turnaround time is 3-5 days to get them back to me via google drive. I need a flat rate quote for all 25 videos and all others through the end of the year.
thanks,
Gary
