Good luck with your career change and don't be off-put by the naysayers. I was two years older than you when I took my ATPL's and enjoyed a great career ending up in the left hand seat of one of Mr. Boeing's machines.
All good advice offered above but if I may add one caveat - do not pay anything up front if you are going down the modular route. A little time spent researching the post in this forum should be sufficient to show you why!
