Theme: FreelanceEngine remove the bidding option and the paid plans

Hello WordPressers

I recently bought the FreelanceEngine theme (https://www.enginethemes.com/themes/freelanceengine/) and I am using it alongside the Jobseek theme so I can achieve the exact idea behind my company’s website. Basically, I am using the Jobseek just for the Homepage, About us and Contact page with some elements removed. The buttons added to the Homepage as well as the pages in the navigation menu bar bring you to the FreelanceEngine theme features. There are two of its features, though, that I would like to remove for now- one is the bidding process and the other one is the paid options. I am new to WordPress and I am not proficient with coding so I asked the theme developers if they could help me with that… And they refused. Now, if I do not make those changes my website would not work the way I want it and all the money and hard work I invested in my project would be wasted. I would be really thankful if someone could guide me and give me any advice on how I can manipulate the theme so that it serves my purposes. I know this include some coding and this is why I decided this is the best place where I can receive answers to my questions because most of the people here are professionals. I am just having my first baby steps into WordPress webdesign but I am willing to learn and advance. I would not mind sending screenshots or login info if someone is willing to help me with this.

Many thanks
