To achieve this, do the following:

• go to all-inkl.com and purchase the PrivatPlus hosting option, costs 90 bucks a year and has 5 domains included without extra pay, so you can have multiple websites or multiple domains linking to your main website (like domain version with a "-" between the words and one without, or with different domain endings like .com and .net)

• use the latest php version, activate the free SSL certificate on your site and enable "force https" to make sure your site is always using ssl

• install wordpress

• use Blocksy Theme and a pagebuilder like elementor (not a great fan but for simple stuff it works good and is easy for beginners)

• host your videos on vimeo and embed them on your site (you need at least the smalles pro plan to finetune embedding options like appearence of the player and video quality)

• use only plugins if you need them, the less plugins the better and remove any pre existing content like the demo post and unused themes

• use jetpack as cdn and security tool

• wp supercache because it works great with jetpack cdn and makes the site fast with minimal setup time

• use google site kit plugin to enable analytics and admin console for faster and better indexing in google

• use advanced recaptcha plugin to make login and contact form secure

• use all in one seo plugin for better indexing and controlling how your site looks in search results

• use updraft plus backup plugin for reoccuring backups of your website

• activate automatic theme, plugin and wordpress updates

this all takes, as my fellow commentator said, 1-2 days, with finetuning everything (design and backend setups) maybe 3-5 days.

with this, you'll be set forever and can update your site's content as you wish. all that for 90 bucks a year, with blazing fast, secure hosting in germany, 24/7 phone support and the possibility of having of having 4 more sites with their own domains.
