English language support?

Hi,
do you provide support in English language?
We are interested in the Chronopay module, so we are interested in buying a license for a Magento and then use the Chronopay module.

Thank you.

Yes, you can ask your questions in English.
Moreover, I have a specialized english-language site for the next Magento generation: Magento 2: https://mage2.pro/categories
When you will considering to create a new store on Magento 2, or to move an existing site to Magento 2, then you can ask questions there: https://mage2.pro/c/ask

Thank you for your answer.
We already have a Magento 1 installation, we need just the ChronoPay module (and its dependencies).
Is it enough to follow the following instructions? http://magento-forum.ru/topic/1003/
Can you provide an invoice for the purchase?
Thank you!

1) Yes
2) It depends on a payment method.
