I've run EE for over a year and used outsourcers to help. I won't name names, but I have not found anyone competent on the Freelancer site, nor Upwork.
Of the people listed here as experts for hire - one failed to complete the task and overcharged cash up front. The other also overcharged and expanded the job whilst stealing my business model and setting up a rival company. At the 60+ euro rate they all want it's a bad decision to use EE.
I had a few Russians when I ran plain nGinx - half the price, twice the service and you could ask a question without getting a minimum 1 hour invoice.
I have therefore decided to use WPOven and WPHostingSpot and sleep well knowing they have the staff and expertise to handle it for me as I work ON my business instead of IN it. Their pageload speeds are pretty similar to what I get - the original advantage of EE was superior speed to nGinx. My rough testing indicates they have caught up.
