Filling the site with Joomla

Good afternoon! I need help with my Joomla website. It's almost done, but I decided to clean up the trash yesterday because The site was made by template and there were a lot of extensions that just hung. I have removed the slider module from the main page. I did a backup recovery through Agave, and manually restored SQL. The module is not coming back. In addition, there is no redirection after the user is authorized to the profile page. You can see and tell me how much it will cost me. I really don’t have the patience to be a dilettante. Just a few more things. Who can do this?
