Job Description

I need someone to take a look at my digital ocean server and optimize my setup. For example, I seem to have a lot of processes running that don't seem to do anything. We are running like 1gb of ram with only 10 site visitors.

The site on the server is wordpress but has a pretty heavy mysql server load due to the shopping cart, during the purchase process we query a 5 million row db.

I also need a mail server setup, I have tried several times with no success. I need to send email receipts after purchase.

I'm don't have alot of knowledge in server management and want some help. I know I'm being vague here but don't know exactly what you need to know, so I'm paying by the hour and we will diagnose together what all needs to be done.
