Wanted : French Consultant for 1800 Euros

Tough times...
Consultant attrition is hard to compensate, and despite the internal calls for recruiting, with a 1800 cash for getting someone onboard, headcounts evolutions are still on the negative side, with many taking the opportunity for a change and a better consideration.
How many years would it take to build the 10+ years experienced consultants we loose ?

Apart from marketing, will we find a way to be the most admired company for the existing employees ?
