Uploading Files within a Laravel Package

I have a file attachment feature in a Laravel package. I want the uploaded file to save in the project using the package and NOT in the package. Currently, the file is uploaded into the package instead of the project.

Controller:

$attachment->spot_buy_item_id = $id;
$attachment->name = $_FILES['uploadedfile']['name'];
$attachment->created_ts = Carbon::now();

$ds          = DIRECTORY_SEPARATOR;  //1

$storeFolder = '../../../resources/uploads';

if (!empty($_FILES)) {

    $tempFile = $_FILES['uploadedfile']['tmp_name'];          //3

    $extension = pathinfo($_FILES['uploadedfile']['name'], PATHINFO_EXTENSION);

    $attachment_hash = md5($tempFile);

    $new = $attachment_hash.'.'.$extension;

    // complete creating attachment object with newly created attachment_hash
    $attachment->hash = $new;
    $attachment->save();

    $targetPath = dirname( __FILE__ ) . $ds. $storeFolder . $ds;  //4

    $targetFile =  $targetPath. $new;  //5

    move_uploaded_file($tempFile,$targetFile); //6

    chmod($targetFile, 0777);

}
else
{
    return "error";
}

Service Provider (I thought publishing the uploads folder might work - nope.)

public function boot()
{
    require __DIR__ . '/Http/routes.php';

    $this->loadViewsFrom(__DIR__ . '/resources/views', 'ariel');

    $this->publishes([
        __DIR__ . '/resources/uploads' => public_path('vendor/uploads'),
    ], 'public');

    $this->publishes([
        __DIR__ . '/../database/migrations' => database_path('migrations')], 'migrations');
}
