Bulk email marketing - 500,000 email blast

Hi, I need to send bulk email in USA, UK. The list is bit Old and hence bounce rate could be high. Requirement. 1) Multiple IP/server to be used for each block. Say not more than 25000 emails sent with the same server. 2) Email should land in Inbox. 3) Analytics/report with open, click, etc. 4) I would prefer to do it myself if you offer service as constant contact. I WILL TEST THE SERVICE PRIOR TO MAKING ANY MILESTONE AND THE TEST SHOULD BE RUN ON A LIST. Thank you.
