Front-end UI designer familiar with bootstrap for tidying up our newly developed admin web interface

We’re in the process of developing a custom admin interface for controlling our digital signage setup. Our system uses data from maritime vessels to geo and time control digital signage screens. Our new version is written from scratch and whole the back-end works great and the front-end does the job, we’d like to tidy it up to give a nicer user experience. So we’re looking for someone who’s has a sense of style, understands UI/UX, and can implement it into our admin front-end using bootstrap.
