Front Running Script - Uniswap

Looking to create a front running script which will work on the ethereum blockchain where contract addresses will be able to be entered, also support private nodes.

What the bot would do:

Scan the blockchain and find transactions based on certain criteria, via mempool

Copy gas price from original liquidity add transaction; liquidity, open trading etc. And apply it to the buy order.

With buy order - be able to enter tokens to be bought with a maximum eth limit

Metamask wallet based, supporting multiple wallets

~~~~~~~~~~~~~~

In other words, need to be able to buy tokens first block everytime supporting multiple wallets.

Would prefer someone who has previous knowledge in working with bots, seeing as i'm quite a newby
