Fix and improve an existent Bootstrap website

Description of every page: We are developing a website and we have a basic design with Bootstrap, so we need design suggestions to improve it.. Among other things we need to improve the following list:

- Fix some of the current behaviors, for example after display results the template moves from the original position, few pixels...
- Change the search results: we used a snippet that is not responsive (bootsnipp.com), also as part of the result we need to add some information like a star ranking
- Make the site responsive
- Add content like images (button, ranking with stars, menu, backgrounds, header, footer, improve the website logo, etc)
- Messages: error (some of them using data annotations) and success messages
- Menu design for two kinds, horizontal on top right and left.

We would like a nice design, similar to a social network.

The site is coded using ASP.NET MVC5, Bootstrap and jQuery.

The site size is about 35 pages (views and partial views)

If you are interested in our project, please contact us and we'll share more information.
Ideas for the visual style: Like a social network
