I do not really think your age is a problem.
I don't understand what's the offer with CAE Ryanair. Have they offered you also TR amd LT?
6500 euro for a MCC is too much IMO, so I'd suggest you to get MCC and JOC at OAA, or if you want only MCC you can find the same course for less, really really less. For example at Kavala you can get it for just 2500 euro.
