Bulk Email marketing 5000 a day

Hello, I need a system or service that can deliver around 1200 emails a day for now. Inbox rate must be around 90%. This means 90% does not land in spam filters. I will provide message and subject, with variations if required. Past relevant experience is a big plus. I need to know how you will be doing the mailings, no details required just to know your legitimate. This is a very small amount of emails to mail, so please no outrageous bids. Cheapest, quality bid wins. Good Luck Bidding!
