At 34 you are at a disadvantage against younger students if you want to make it your profession. You might get to Captain on an A319 at Easyjet but you re unlikely to make it to captain on a 747-400 before you retire if you start the career at 36...
The best type of learning is full time courses but you need to be able to take a good year off work and it costs a bundle.
Are you chasing a dream? You own several businesses, as a commercial pilot you ll be employed by someone else..... Sure you want that?
Perhaps get your PPL followed by a multi engine rating and an Instrument Rating and build your businesses in such a way you can justify flying yourself to your customers.....
