Green Geeks hosting

for Codeigniter - they don't need to "support" codeigniter - you can use any hosting company that supports PHP. they look interesting for sure. did a quick google search and they started offering PHP 7 in January which is respectable.
and they took the time to explain to their customers why its important.
