I'm confused, you have a CPL but the biggest plane you've flown is a 172?
Also you have your first job and you have "nothing" to stand out... You're up against people who have never worked in aviation. What kind of job are you after?
To answer your first question, there is no magic site to find work. Not many companies advertise vacancies unless they're desperate.
Finally if your english isn't great take time to spell check (even on here) and get your mum to go over the spelling and grammar.
