Hello
I am a science faculty and I am into education for the last 6+ years, dealing with Chemistry, Physics and Maths upto college level. We have subject specialist for each subject and well versed with entire chemistry category.
I can easily do it within a very short span and with proper classification. Perhaps you forgot to mention the number of videos, if the number is less we can then do it at a cheaper price.
If we need to discuss it further skype/mail- catchvictor/catchviku at gmail.
Thanks
