How ia the Future for a SAP FI/CO / PS Consultant ?

Hi, im now 5 month in the SAP world as a junior Consultant. Currently we deploy the PS Modul by a Big customer in Germany, while I am learning for the fi co certification. My Goal is it to become a Freelancer in 3 years. I startet with 50k. Is 100 k Minimum in 3 years with certification and a Lot of Projects realistic? Is the market getting more attractive, because of the conversión to s4hana? What would You Say? My Background is Finance, thats why i choose These modules to become expert..
