In short, no to both internal/turbo-prop!
If coming from a commercial background you must have an Airbus or Boeing rating and experience with 3000 hours, 1000 on type. If coming from a military background you will need to have 3000 hours which must include at least 1500 hours 'heavy' experience. You must hold a current Class one Medical and a full JAA ATPL licence (UK issue) - for military pilots a frozen ATPL is acceptable. You should be able to demonstrate a high level of fluency in English (ICAO level 6 English Proficiency).
Could be wrong, but don't think VS have ever done Cadets or "Pay to Fly" donkeys!
