5 years? Definitely achievable.
1. Get your licence (12-18 months)
2. Go north and get 1500 hrs (24 months)
3. Join regional, work for 18-24 months
4. Get yourself on a jet or stay in the regional. Either way you're doing the RPT thing.
If you want to make it happen quick, don't piss-fart around instructing at your local. Get out of town, go north and get it over and done with. Just like pulling off a band-aid.
Very doable this day in age (provided no big delays between jobs or getting the first job). And remember, there are many ways to skin a cat.
Don't forget though, despite the band-aid comment, it's all about the journey isn't it??? You may just want to push out that 5 years a little longer if you love what you're doing. I can definitely vouch for that. Good luck.
