To put things in another perspective, the Ryanair TR is maybe the cheapest one you can do out there (despite the regular price increase, it was only 27 000 euro a few years ago). The reason being it's your company that pays for it, not you with your privately earned, taxed, money.
New cadets at Ryan are all paid via storm contract (the new and improved Brookfield......) which means after the sim duductions of 4.50e per hr you are paid <500 hrs on type 50.50e, after 500hrs on type (about 7 months on line) 65.5e, and after 1500hrs 70.5e. Full time Ryan contracts vary by base and country, and the storm contract is paid that rate regardless of base. Once eligible for upgrade you can get 8e an hr extra, and any out of base you get additional 20e per schedule block hr. All pay is schedule block, so when the French strike and your on ground with a slot it's all unpaid...
All the same as the Brookfield except the rates have been dropped when > 500 hrs, >1500 hrs and the 'command ready' rate.
What is the payscale for experienced FOs? ie 5000-ish hours on type?
Experience (or loyalty) is not valued in Ryanair. You will earn the same as all other FOs. With that I mean, there is no special contract for you just because you've got plenty of hours. Contracts vary by base.
