Estate Agents
As an Estate Agent, you will doubtless be good at understanding a client's requirements and then matching them to suitable properties.
Recruitment is effectively the same type of process - understanding what a Company is looking for in a new recruit and then supplying them with candidates who match these criteria.
Using your estate agency background as a starting point, you should be able to rapidly adapt to the demands of recrutiment and start earning some serious money.
