this is an ERC20 token

What is your experience with writing smart contracts on ETH? We want to create a token that does the following: - Staking and rewarding the stakers with a % of the amount they staked so basically something like 5%APY (to be confirmed) - Unstaking penalty/fee - a % of the amount unstaked (small one) and part of it to go to treasury, part of it back to stakers and divided equally to all stakers and part of it to be burned. - Yield farming (to be confirmed by you how this can work and if we can also implement this feature or it will be in contradiction with the staking rule? If you can elaborate on this would help us understand our options better - Voting rights so the holders of the token to have voting rights - still not sure about how this can work if we need a dapp or we can use a third party service for this. - Also have a fixed total supply - initial supply will be x amount and the rest to be either minted trough staking or yield farming or even both if is technically and logically possible Please advise further Thank you
