Amazon EC2 WordPress High-Performance Hosting Installation, Configuration & Migration Service
We can do everything described in this article: Host a super-fast WordPress site on Amazon / EC2 — same price or less as conventional shared-server hosting. What you are getting here is performance comparable to a $35/mth WP Engine Startup Plan, with the added bonus that you can host unlimited sites with unlimited traffic. Your recurring cost for this (paid to Amazon) will be roughly $8/mth, and may be free for the first year.
Note: this service is limited to 2 hours of developer time. The work of migrating complex sites or adding additional sites would need to be purchased at the rate of $40/hr here.
If you are not clear what you want or if this is for you, purchase a super-affordable consultation.
