Modify Javascript Crypto Sniper

How much would you charge to help me. I need to modify a java script I had made by someone else a while back. It is Sniper for Pancake swap Exchange. The sniper Takes a contract address that I input from bscscan.com and sniffs the mem-pool to see when liquidity is added so that it can snipe the listing and be one of the first buyers. If no liquidity is detected it keeps checking until it added. What i would like modified, is that i would like it to check multiple contract address. So when I start the script, I would like it to ask How many Contract Addresses, then ask me for each Contract address, and then after Check for liquidity added constantly for each added contract address. when Liquidity is added it will snipe the listing and then proceed to continue looking for liquidity added on the another pairs.
