build a website for business purposes, sometimes so hard for me, because I as a novice in the world of web. is there anything that can give advice, especially with using drupal cms.
What kind of advice you need? Just go for any CMS like Drupal, Wordpress or Joomla and start using it.
You can watch a lot of free tutorials on Youtube about Drupal, and then it's just a matter of trying and testing it out. Good luck!
