How can I order the free installation service?

Hello,

I am about to go-live with a large Magento site (2.2.1)

How do I order a free installtion of Strip[e for my DEV and PROD environments?

You should buy the license first.

Hello,

Thank you. I will do that after testing your free installation.

Would you be able to look at my installation if I gave you SSH access?

I am getting the following error after installation:1 exception(s):
Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid XML in file /var/www/html/sites/www/vendor/mage2pro/stripe/etc/adminhtml/system.xml:
Element ‘dfExtension’: This element is not expected.
Line: 23

I can confirm stripe has been downloaded and installed

I do not work for free.
