Bulk Mail Solution With Multiple SMTPs and IP's

We need a bulk mail solution on our dedicated server with multiple SMTP's, bounced handling, SPF/DKIM etc. Inbox delivery is 100% must. I t doesn't matter if you use OEM Pro, pre-warmed up IP's or whatever method, I want the job done right with a long-term goal in mind. It should be a proper setup with inbox delivery as the highest priority. The mail should reach the inbox and not the spam/bulk folder. We have a 100,000 email list of our customers, these customers know where they are receiving their emails from so the spam complaints are very low on our email list. We need a good coder who knows how to get to the inbox especially Gmail, Yahoo, Hotmail, AOL. Please do not bid if you do not already have feedback from other projects similar to this. We are looking at OEMPro as our email software if you have any other suggestions please let us know. Note: Long term related projects and a good monthly maintenance fee are possible if the coder is good and you do a good job.
