HW,
As said by old scroggsy, advisors for training are a bit thin on the ground. Personally, I found a certain book by a certain Mr Clive Hughes was a god send in information.
Then I discovered pprune and the rest is history.
However, to add my veiw in your situation. Go modular, do an FI to build your hours and then apply to the regional TP outfits. The mob I work for have given 3 FO's over the age of forty their first twin turbine job. And as a ratio we only employ a total of 15 drivers.
