Operating manual for smart contract and other jobs

I have two smart contracts deployed in BSC network.
One is smart contract with buyback function and the other is one for staking.
I need to have detailed operational manuals for these smart contracts.
I need to have detailed functions and operating manual with examples in word file.

Attachment is original smart contract that I forked.
You can describe me each function of read and write contract in BSCSCAN.
Again, I need to learn how to operate these contracts.

Second job is integration staking smart contract into Dapp.
Both were created by https://www.cues.sg/
Manual is at https://www.cues.sg/guide
All design is ready to go and smart contract has been deployed in network.
I need to integrate them and deploy it in my homepage.
I need to learn how to handle this jobs so you need to work in my computer using teamviwer or Anydesk for second job.

Please reply it with final cost of work.
