Deploy smart contract on Ropsten using truffle-hdwallet-provider

Question

I have 7 smart contracts to deploy on the Ropsten network.

I am using truffle-hdwallet-provider and below is the content of my truffle.js file:

module.exports = {
  solc: {
    optimizer: {
    enabled: true,
    runs: 200
 }
},
networks: {
 ropsten: {
  provider: function() {
    return new HDWalletProvider(
      process.env.MNENONIC,
      `https://ropsten.infura.io/v3/${process.env.INFURA_API_KEY}`
      );
    },
    gasPrice: 250000000000,
    network_id: 3
  }
 }
};

Then I run the following command:

truffle migrate --network ropsten

but I get the following response:

Error encountered, bailing. Network state unknown. Review successful transactions manually.insufficient funds for gas * price + value

Fine, it stated I have insufficient fund and my fund was 1.509 Ether at the time. So can I assume the cost to deploy all my contracts is more than 1.509 Ether (that's more than USD163!)?

Appreciate if someone can guide me.

Try this to find out Gas Usage : https://github.com/cgewecke/eth-gas-reporter

Also just try removing gasprice from truffle file and try again
