OK. Don't go on the course.
Instead do a PPL. Keep in employment. Build towards 100hrs. Add an IMC. Take your time, enjoy your flying, join a club. Maybe join a syndicate. Start the distance learning ATPL groundschool. Study after work and at weekends.
Then maybe as soon as 2 years from now look again at commercial aviation.
I think you'll be very glad if you do that.
