Wordpress expert to update salient theme and salient visual composer

I have a site that have salient theme and salient visual composer. I attempted to update but it threw few errors. I need a wordpress expert to update and fix the errors.

You are to update Salient Theme and Salient Visual Composer to latest versions and have the page builder work as it should, and the front end of the website appear as it should.

This is a dev site so after update move it to the live server.
