Hi,
I think I've already seen the same project description in the past, not sure if you had posted the project here on Freelancer or some other marketplace in the past. I'm Ahmad from the team, and we can help you set-up exactly the infrastructure you are looking for. All of the requirement list will be carried out in the solution we will provide you, just, the deliverability needs to be understood more clearly. Deliverability depends on several things including your list, content, sender reputation and the niche as well. Can you please address the following.
How hygienic is the list you are looking to send to?
Which niche you are targeting? some content needs inbox critical strategy, especially across the major ISPs (Gmail, Yahoo, etc)
What's the portion of Major Email inboxes (Gmail, Hotmail, Yahoo, etc.) in your list?
Let's move forward in the right direction, I look forward to hearing back from your side.
Regards
