Translation of Videorecorder

I want to work on the country specific terms first, then do a revision of the words that we have entered so far... please give me a few days to finish it. However, I may need to contact you over the weekend, depending on my progress.
My correction were added and highlighted with yellow markers and attached to this email. Tell me now if you have any questions about grammar rules, since I was a teacher 10 years ago.
I would also like to thank you for your interesting phone call on Friday 4 weeks ago. As you have proposed at that time, I will bring up a few ideas for possible cooperation in the future.
