Looking for reliable SMTP or setups

Hello, I am looking for reliable SMTP to use in mailget, since Amazon SES has a problem with my list. I am looking for eithers reliable SMTP details or for someone experienced who can setup a very good and reliable server solution for sending.

I have about 5k emails, won`t be sending daily, maybe only weekly or 2 times a week.
