That markets been slaughtered for a while. Pretty much every big tech company has built up strong internal security teams and automated as much as possible. Look up what happened to NCC Group post Matasano acquisitions, I joined within a year of the isec/matasano/intrepedus acquisitions and saw a slow ride down. After 5 years the rate was still $2500 a day and everyone with real talent left to internal teams for much much higher pay. NCC Group is now a scan shop operating out of the phillipines, I still have one friend that works there from the isec days! The exception being some leet places like Trail-Of-Bits.
