Deploying a contract with a "payable" constructor and including input parameters?

Question

There is a useful Solidity contract HERE. However, there are two things at time of its deployment:

(1) The first thing is the contract balance since its constructor is payable. (2) And the second one is the constructor's parameters value ((address **_recipient**, uint256 **duration**))

To deploy a contract I use web3.js 1.0.0-beta.34. Here is the steps I do to deploy this contract:

Web3 = require("web3")
web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

const bytecode = '0x1234 ....
const abi = ....

web3.eth.personal.unlockAccount('0x123...', 'password')

var thisContract = new web3.eth.Contract(abi, {
    from: '0x123...',
    gasPrice: '20000000000'
});

thisContract.deploy({ data: bytecode }).estimateGas(function(err, gas) { console.log(gas); });

thisContract.deploy({ data: bytecode }).send({
        from: '0x123...',
        gas: 5000000 ,
        gasPrice: '3000000000'
    },
    function(error, transactionHash) {
        console.log(error);
        console.log(transactionHash);
        console.log('function exec');
    }).then(function(newContractInstance) {
    console.log('Contract Instance:' + newContractInstance.options.address);
});

However, I do not know where in the above process I must determine (1) the contract balance (since its constructor is payable) and (2) the constructor's parameters value (i.e. (address _recipient, uint256 duration)) ?

Note: I guess first I have to deploy this contract using remix where I determine the constructor's parameters values and then use generated bytecode and abi by remix in the web3.js above code. However, I am not sure where can I use value: web3.toWei(1/*contract balance*/, 'ether').

Have a look at the example:

const thisContract = new web3.eth.Contract(abi);
thisContract.deploy({  
        data: bytecode,
        arguments: [ "0x2345...", 12000 ] &lt- Here you put your constructor arguments in order
    }).send({
       from: "0x1234...",
       gas: 5000000 ,
       gasPrice: '3000000000',
       value: 120 &lt- Here you put how many wei to send to the constructor
    },
    function(error, transactionHash) ...
