New Commenting Script for HTML Site

We are currently using a commenting script called Disqus.com. That system requires all posts to show the date of each post. We hired a Freelancer to remove the post date function without also removing the posters name. They fixed it - so each post shows the posters name and NOT the date - which worked perfectly. Disqus recently updated their system so users cannot use any custom coding on it (at least that's what another Freelancer told us) and now every post is showing a post date again. We need to change commenting scripts but the end results we want is for it to look the same as our current Disqus setup, and still include ALL the comments which our past customers have already uploaded into the Disqus section. The script is running on 6 pages of our website - so all six pages need to be fixed. We will give access to these pages to the winning vendor.
