I have a website designed on joomla (www.uni-prep.com). It was designed by someone based on a template. The website takes a long time to load initially. I believe this is because there are a lot of extra things on the backend that don't need to be there. I need someone to make the website load faster by removing the unnecessary components and whatever else you think makes the website slow.
I also need a few changes made to the website. I need to:
1) add a calendar for upcoming courses to be put on the front page.
2) the website isn't accessible in some regions and I need to find out why and fix it
3) change the logo
4) change the logo that is visible in the browser tab
5) other adjustments as they come along
