Bypass google translate translation restrictions?

Question

Google

We need to translate a little less than 2000 requests. Do not stuff into one.
Google gives a limit per hour of 100 requests, stretching for a day is not an option.
I slip him a proxy, does not allow him to connect.

The library I use - https://github.com/Stichoza/google-translate-php

$tr = new GoogleTranslate('ru', 'en', [
        'timeout' => 10,
        'proxy' => [
            'https' => 'http://201.217.55.97:43110'
        ]
    ]);

Proxies are free ....
Maybe someone knows what translation service?
All you need is one time.
