Change a BSC Contract and show me how to deploy & edit it afterwards. Also you need to know DXSALE!

Hello, i am looking for a expert regards Binance Smart Chain. we are looking to create our own Token to list it on Dxsale. We already know how to create a Token, but we need someone to change the Contract a little bit. Also we want to release the Coin on a Launchpad called DXSale where its necessary to change the Contract a little bit after we already created the Token - we need to know how that works! For example it looks like this: 1. setLiquidityFeePercent to 0 2. setMaxTxPercent to 100 3. setSwapAndLiquifyEnabled false 4. setTaxFeePercent 0 5. ---- 6. Test your code on the test networks provided 7. Call finalize 8. setSwapAndLiquifyEnabled true 9. setLiquidityFeePercent (To your lp tax fee amount) 10. setTaxFeePercent (To your reflect fee amount) Show us EXACTLY how are able to do this after we already created our Token! we are pretty newbies in that section, so we need an helping hand here!
