my model name hiring.php

<?php

namespace App;

use IlluminateDatabaseEloquentModel;
use IlluminateNotificationsNotifiable;

class hiring extends Model
{
    use Notifiable;
protected $fillable = [
    'name','email','subject','message'
];

protected $hidden = [
    'password', 'remember_token',
];
}

my controller named mainController

<?php    
namespace AppHttpControllers;
use Apphiring;
use IlluminateHttpRequest;

class mainController extends Controller
{
    public function index(){
        return view('main.main');
    }
    public function store(Request $request){
        $hiring = new hiring;

        $hiring-> name = $request->name;
        $hiring-> email = $request->email;

        $hiring-> message = $request->message;

        $hiring-> save();
        return view('main.main');
    }
}

My table is following named create_hiring_table

<?php

use IlluminateSupportFacadesSchema;
use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;

class CreateHiringsTable extends Migration
{
    /**
     * Run the migrations.
     *

        Schema::create('hiring', function (Blueprint $table){
            $table->increments('id');
            $table->timestamps();
            $table->string('name');
            $table->string('email');
            $table->string('subject');
            $table->string('message');
        });
    }

    /**
     * Reverse the migrations.
     *

     */
    public function down()
    {
        Schema::dropIfExists('hiring');
    }
}
