Nope!
You gotta start your career from the scratch.
There is no way arround it.
Start by flight instructing or fly parachute jumpers.
Thats the best way of getting the valuable experiences, there is no shortcut.
Don't be to optimistic by wanting to fly only the jets, with only 300 hours
you have to face a very tough "competition" from thousand hour pilots.
Be realistic and respect your job.
Cheers.
