How To Do Ddos?

Some competitors regularly order DDoS for my website. I want to respond in kind and order a return DDoS. How much does this service cost and how to do it?

 

What can you advise to do in such cases?
I saw such prices on http://wtj5psom5zufu4yo.onion forum for DDoS services.

 

1 hour - from 20 $
12 hours - from 40 $
24 hours from 65$
1 week - from 350 $
1 month - from 999$
I just looked, are you talking about these prices?

 

Well, these are reasonable prices, I would use it.
