Edit and Add additional features to php/laravel codecanyon script

I bought this codecanyon script: https://codecanyon.net/item/investorm-advanced-hyip-investment-management-platform/32431844 and I would like to add some additional features like an MLM referral system with tree view, I would like to integrate crypto's market graphs in a page on the user dashboard and I would also like to add a feature to the investment plans and make them dynamic by adding manually the transactions made from the admin's dashboard.
I will provide the code for the script, I expect the same design to be used for the new features and pages.
Please apply to this project only if you have experience in php/laravel and have at least a basic understanding of MLM and investment systems.

Thank you
