Need web3 application built for NFT project.

I have an NFT project that i need a web application built for. I am looking to allow people to visit the website, connect their wallet and show which tokens they own along with serving them 2 files (one audio and one jpg) that they can download. However, they will only be able to see these if they own the specific tokens according to those assets. It'll also need to serve the metadata on page. We need a complete design & functional application. Must be built in reactjs and use web3 along with web3modal. Ideally we would like to have this completed within a week.
