ok, but tell me. You know those technologies, do you think, yes or no, that for two small blog-like sites, 600 € annual maintenance fee is justifiable ?
Not only justifiable… but the industry standard for Managed WordPress Hosting:
https://www.savvii.com/managed-wordpress-hosting/ => starting at 468 euro per year
Pricing - Kinsta® => starting at 420 per year
Note that static hosting up to 100 websites is completely free at Kinsta!!! I could host ALL websites from cms.usecue.com on one free Kinsta instance (but trust me… I won’t). I hope this makes you realize how much more time and resources hosting a WordPress website takes.
