Hello Sir,
Greetings!!
I have gone through your requirements regarding changes in your WordPress website.
I have checked each point that you have mentioned.
Here I am giving you my views as follows:
1. I will make a different sidebar for others page of your website which contains item "pages". You can change the content of this.
2. I will remove the comment section on all the pages of your website.
If you have any questions or would like to discuss your project further, please don't hesitate I am available via phone, email or Skype. Many thanks and have a lovely day,
Thanks & Regards,
Rahul Sahu
