Two Magento Tasks - Magento 2 Install on AWS EC2

Have a brand new instance on Amazon using Magento 2 image. I have two tasks for an experienced Magento developer. Reasonable bids only. See my feedback, I pay promptly, but have no patience for high bids. ISSUE #1: Install went great and login is good, but the second I started to change my admin password, the system reported it cannot send email. Need to resolve this so I can move forward. ISSUE #2: I have a third party extension (not on Magento Marketplace) that needs to be installed. It is a small extension, a Stripe payment gateway, essentially. I don't need help configuring it once installed, I just don't have experience with Composer or installing extensions outside of the Marketplace. Should be two very fast projects for someone with Magento experience. Reasonable bids only. Thanks--
