my competitor is doing a denial of service attack on my site..suggestions?

One of my competitors has been doing a ddos attack on my site for the past 2 weeks, he's managed to take it offline for a few hours at least 3 times. Its been confirmed that its denial of service by the hosting company.

My question is, for anyone who has experience with this, is there anything I can do to combat this that doesnt involve buying a $5000 server? Are there companies that can help to locate or prevent this?

And this being blackhatworld..once I find out which competitor it is, is there anything I can do send him a message to knock it off? Im open to all suggestions, if they're less than.. civil then feel free to PM me..

I would greatly appreciate any knowledgable persons advice on this subject.

thanks..

You can use cPanel to block IPs or use .htaccess to do the same. If you can trace the IP back to the ISP you can report an abuse incident with the ISP

What i would do is check the access logs to see all the "zombies" hes using to attack your site, most hosting providers have an IP ban option, mind you if this is a large ddos there will be a ton of IP's in that file and it may be a pain to sort through them all unless you wrote a script to extract them all for you. After that add them to the banned IP list
