I am perfect for this ;)
First at all, i am very expirienced in DDOS in all types of them, HTTP/SYN/UDP/TCP ...
I can even tweek your kernel for some kinda attacks, web server for slowloris defense, cloudflare is good but it also have some thinks on what people don't pay attention, and i am 80% sure i can retrieve your web server real IP even if it is on cloudflare.
I am linux maniac, mostly debian/centos (my choise) so i can perfectly setup your webserver to have no problems.
I need 1 day for this, but in case i am too busy or you request something else than i will need 2 days.
I set up this price because i want to make good reviews for me, and this is something what i know very good.
