I'd like to hire a real Expert Ethereum Smart Contracts developer

1. Please make the main diagram shows Smart contracts and the relationship between them for this project and show me, so prove you're just the best fit for it. (The detail explanation for this project is following)

2. Please show me the example of Smart contracts(customized ERC20 token, ICO, crowdsale) you developed.

1) Utility token smart contract - for ICO and distribution on Etheruem network

-ERC20

-180,000,000 total supply

2) Room Token smart contract to buy it optionally during or after the ICO with Utility tokens

- mintable and burnable by contract creator (for new resorts or lost tokens)

- 23,750 initial total supply

- NFT tokens (ERC 721)

- price: 2500 utility tokens (it changes depending on season) (they get locked and can be returned after 1 year period, if you lock for 2 years or more you get more back - if you wish to unlock earlier you get a penalty)

at the time of buying you add :

variables

- date

- room number

3) timeshare multisig smart contract - for sharing room tokens and rewards in utility tokens

- multisig

- oracle input from our calendar: the guest chooses his time period to share his room token and then for that time period the room token is not available to him but to us ("the resort"). we then forward the temporary permission to use to token to another guest (to his eth wallet if he is a crypto customer or we put it on a hardware wallet and give it to him at the arrival to the resort or we just keep it for ourselves if he doesn't care and is not coming 100% anonymously )

-after the renting period is over the room token is returned automatically

- monthly payout in utility tokens to the token holder depending on if the Room was rented

- a fixed amount of utility tokens reward is sent to a special wallet for charity

4) zkSnark password to prove that you own the room token on your wallet at the arrival to the resort

5) biometrics on eth wallet for door unlock (you don't need a pass anymore, you prove token ownership with a fingerprint)
