Develop a WordPress plugin

Project Desciption

I need a developer who can create an add on plugin for the beaver builder WordPress page builder. It should be extremely light weight and clean code. Here is a description of what is needed in the plugin, etc.

As of now when someone uses the beaver builder to create or edit a page in WordPress, users have the ability to change and edit all aspects of a page. They can change font sizes, margins, paddings, weights, etc… I need a plugin that limits an “editor role” to only change text, pictures and colors. All other aspects of the page builder should not be editable by an editor role. Everything should remain unchanged for an administration role though. 

Please provide your bid and timeline for completion if you are interested and are very sure you can accomplish this task to the highest quality.
