URGENT : Fixing Joomla index.php file CPU problems

I don't know how I should describe this project as best but i'll give it a shot. My hosting account got suspended because the [login to view URL] file was using too much CPU on the server. Now I have a few days to fix the issues. The [login to view URL] file is a joomla file, my joomla index page. This is the 'error' codes they've got 21807 21153 marion2u 643 26 10 202m 30m 7512 R 94.5 0.8 3:45 /usr/bin/php /home/marion2u/public_html/[login to view URL] 21807 21153 marion2u 643 26 10 202m 30m 7512 R 97.3 0.8 3:59 /usr/bin/php /home/marion2u/public_html/[login to view URL] 21807 21153 marion2u 643 27 10 202m 30m 7512 R 97.7 0.8 4:08 /usr/bin/php /home/marion2u/public_html/[login to view URL] 21807 21153 marion2u 643 26 10 202m 30m 7512 R 96.3 0.8 4:18 /usr/bin/php /home/marion2u/public_html/[login to view URL] 21807 21153 marion2u 643 27 10 202m 30m 7512 R 91.7 0.8 4:38 /usr/bin/php /home/marion2u/public_html/[login to view URL] 21807 21153 marion2u 643 26 10 202m 30m 7512 R 96.3 0.8 5:06 /usr/bin/php /home/marion2u/public_html/[login to view URL] This file was using too much cpu they say. So now I need someone who can fix this properly. Paying 30$ for the one who can fix this.
