Ethereum Dapp Frontend

Hey, we essentially just need someone to modify the Uniswap front end slightly (current or past versions, TBD, at least UniswapV2). We essentially want to add limit orders to the front end by connecting to our project (stealth mode). It doesn't really matter how the automation works - all you need to know as the front end person is that we need the front end to call our contracts instead of Uniswap's. This is going to get a bit technical so if you don't fully understand, please don't apply ;) Currently the Uniswap frontend obviously calls the Uniswap contract. We need to turn the instant swap in to a limit order by adding a price that the user wants the trade to execute at. When the user clicks 'swap', instead of creating the swap transaction and broadcasting it via MetaMask, we want: 1. The transaction to be created but *not* broadcast 2. The calldata of that transaction to be extracted (i.e. the function sig + hex, i.e. what you see under 'input data' on Etherscan) 3. That calldata to be used as an input for an actual transaction to our contract that is actually broadcast. So in total, only 1 transaction happens on-chain (step 3), but 2 transactions are constructed locally. We also need the name and logo etc changing, obviously that's easy. So overall there technically shouldn't be much modification needed to Uniswap's front end - just need to basically add an extra transaction to the flow of the logic when a user hits 'swap', while preventing the original Uniswap tx from being broadcast. We would like this to be done ASAP - some frontend friends have estimated this should be able to be finished within 2 days easily if the dev knows what they're doing and has some familiarity with the Uniswap code. Previous work creating frontends for dapps and especially Uniswap-related is a HUGE factor in deciding who to pick :) Thanks!
