Hello,
So your theme is based on elementer plugin, I have experience on this plugin, its one of my favorite builder plugin.
So, I went through the document file that you attached, and it seems clear plan for the website changes. I can surely help you get this done, and any sort of help that you need to launch the website.
Lets discuss over chat if you are available. So we can plan things accordingly.
If you have any query, I will be happy to answer.
Thanks
Sanket Raut
