Crypto wallet

I'm looking for a reliable and secure cryptocurrency wallet to store my USDT/BTC/ETH tokens on a web platform. This wallet needs to be highly secure, and possibly even feature multi-signature functionality, although I'm not sure if that's necessary yet. The chosen freelancer should have experience in setting up such wallets and be able to demonstrate a good track record of developing cryptocurrency wallets. Payment upon completion. I also want to connect this web to a perfect money wallet.
