How to display admin answer first then display another answer

At the moment, the plugin does not support this issue, if you want to have it, we are ready to help you as a custom work with a charge of fee. In case that you are still interested in the feature, please kindly let us know, we will check and estimate the time.

Sounds good!
Can you please let me know the estimation and cost for this?
My requirement is as follows:
For each questions there are answers of mixed users and admin. What I want is to display all answers by admin first and then all answers by other users date and time wise with pagination as it is right now.
Let me know if you have any query here.
Thanks
