How to lock liquidity on pancakeswap?

I need to lock my liquidity on pancakeswap so as to step forward towards trust. Also, I need to lock my DEV wallet so as to prevent extreme selling volume from the devs.
But whichever service I am visiting, they are costing a lot for it. One service almost cost 1.5BNB’s. Others ask for 0.4 BNB which is still a lot for us.

  1. I have a doubt that if they can lock our liquidity, why can’t we ourselves? Searched a lot but haven’t found any help. Could someone please tell me how can I lock my liquidity and dev wallet myself?

  2. I need to serve my token so that people can buy it, but I am really confused on that. Some people said send it to the contract address and others said put all into liquidity. Can someone clear this doubt?

Thank you!
