Hi, sir. I have carefully checked your requirements and I was glad that I've already done this kind of projects before. I'd love to share more detail with you over chat and I'm sure that you'll be interested in them. I also have very much experience in all skills you wanted for this project, Email Marketing, Email Handling, PHP, Software Architecture, MySQL, so I think I can be the best candidate. Please contact me so that we can talk in detail.
Thank you in advance!
