Hello, I have gone through everything you have said and need to clarify a few things,
1. I will need user access to our website to record the screencast,incase the account needs to be premium, you shall provide a demo account, are you okay with this?
2. Each video part will take around 2-3 days to complete, So I will ned about 10-15 days, does this time frame suits you?
3. please clarify this satement, "I will need 4 series of systems like this series".
I am very professional and my feedback and completion rate reflects that.
Please reply if interested, we can discuss further. Thanks
Regards
