Build an NFT Marketplace with my theme -- 2

I have purchased a NFT Marketplace theme from themeforest and would like to develop the functions in the theme which include buying, selling, minting of NFTs and other functions listed in the menu like galley, profile etc. Please Note : I have posted this project several times and i have been scammed & raised several disputes due to freelancers not responding, hence i will not be communicating outside freelancer & payment will be done only after the project is complete.
