I have great experience in building Web-based Email Platforms that send emails through Amazon AWS SES. I can build your project for you VERY quickly, just so long as you create your own Amazon AWS account. Ongoing, the emails will cost you $1 for 10,000 sent emails.
I have screenshots of past jobs very similar to this.
I will also make myself available on an ongoing basis for advice if you need it, even after the job is over.
