Smart Contract and Pancake Fork

We need to create a new smart contract which included minting and halving features. And need to work specific fork of pancake customized for us just staking and reference model features. And the pair will be only BNB/our token, USDT/our token is enough.

Halving details:
Finding the maximum supply and performing a function like the one in MBOX.
There should be a year-specific mint limit and distribution should be made according to this limit.
Web3.js should be ok. The swap we will make must be suitable for our platforms. For example, it is suitable for the staking platform. like this:

“uint256 decimal = 10 ** uint256(decimals); /**
* There will distribute 400,000,000 Mbox in year 1
* 225,000,000 Mbox in year 2
* 175,000,000 Mbox in year 3
* 125,000,000 Mbox in year 4
* 75,000,000 Mbox in year 5
* In the future, up to 50,000,000 Mbox can be released each year */ maxMintOfYears[0] = 400000000 * decimal;”

3% fee on every transaction:

1% Burn:
1% Another Fee
1% Marketing Fee

Other smart contract details will be discuss.
Need to test it on testnet before and then if we are agree go for live.
Deadline is 3-4 weeks.
Thanks in advance.
