As Capot says.
Your best bet is to try and get on the books of a contract agency, however if you have no hands-on experience and only theoretical qualifications you may struggle to find one that will take you. Consider starting by offering free help to a local flying club, and tell the contract agencies you are available for unskilled work. Once you can get some track record you may find more interesting work opens up. Continue this for 5 years, do a good job, build up a toolkit and you may get what you need.
