    My ecommerce site is under DDOS attack. I am looking for a way to find the source, if possible. $ for the right person that can find this information and any pointers are appreciated even if it's just to get a ddos filter service immediately.

    php script wont work for ddos attack as it uses just as much resources as your index.php getting hit. You need to stop it on server level using firewall script, tcp stack tuning, etc;
    csf with connection tracking on reasonable levels, http server optimization - litespeed or lighttpd is best, apache is just not good for ddos. There is lots you can do. Just google it

    Parse webserver and netstat logs and find DDoSing IP's then block them. After that install CSF and much more lighter webserver like nginx

    Thats probably not a right idea! You can withstand a pretty good ddos attack with apache event mpm. This MPM maintains a pretty similar structure like litespeed. Though, a decent Idea could be to employ a nGinx web server front-end to be used as a reverse proxy. This works fine almost all the time.
