ICO token presale dapp with Smart Contract

Hi, we need a smart contract for an ERC20 token presale similar to: [login to view URL] -The smart contract/ dapp should have multiple "phases" with different token price for every phase. - The token sale dapp should be accessible with both metamask and "wallet connect". - Users should be able to buy tokens with ethereum and erc20 stablecoins (USDT, USDC, DAI etc...) -The Token sale dapp should have a percentage (%) bonus system based on the amount of tokens bought. -The token sale dapp should have a referral system for which a referral link gets generated when the user connects their wallet and they should receive token rewards when other users buy from their referral link. -The dapp should have a leaderboard for ranking investors based on the amount of token they bought. -the dapp should have a mini admin dashboard accessible only to the smart contract deployer where we can withdraw raised funds any time from the pre-sale contract and adjust the dapp settings. Only send a proposal if you have previous experience with smart contracts and dapps and only if you have previous work to showcase. thank you.
