Flight Instruction, Bush Flying, Light Twin Charter, Fire Patrol, Traffic Watch, etc....
All of the above are good options for gaining some experience. Do that for some time and you will have the requisite flight time for your first turbo prop or, if you are lucky, jet job. Unless you are a local of a country with a national airline don't expect to start your career in a 777. In my case it took 7 years to land a jet job. A lot depends on your region and the state of the industry.
It might help to contact successful pilots from your region who can give you advice/ideas. It can be a long road but if you are persistent and work hard you will get there.
Don't buy your job...the pay for right seat flying time scams won't lead you anywhere worthwhile in my opinion.
